Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997886, here are decompositions:

  • 7 + 997879 = 997886
  • 73 + 997813 = 997886
  • 79 + 997807 = 997886
  • 103 + 997783 = 997886
  • 193 + 997693 = 997886
  • 223 + 997663 = 997886
  • 277 + 997609 = 997886
  • 313 + 997573 = 997886

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 997,886 and was likely granted around 1911.

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

Position in π

The digit sequence 997886 first appears in π at position 408,246 of the decimal expansion (the 408,246ordinal-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.
