Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621038, here are decompositions:

  • 29 + 8621009 = 8621038
  • 89 + 8620949 = 8621038
  • 191 + 8620847 = 8621038
  • 197 + 8620841 = 8621038
  • 281 + 8620757 = 8621038
  • 311 + 8620727 = 8621038
  • 317 + 8620721 = 8621038
  • 347 + 8620691 = 8621038

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,621,038 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8621038 first appears in π at position 565,905 of the decimal expansion (the 565,905ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
