Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938890, here are decompositions:

  • 11 + 938879 = 938890
  • 47 + 938843 = 938890
  • 59 + 938831 = 938890
  • 83 + 938807 = 938890
  • 317 + 938573 = 938890
  • 353 + 938537 = 938890
  • 383 + 938507 = 938890
  • 431 + 938459 = 938890

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 938,890 and was likely granted around 1909.

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

Position in π

The digit sequence 938890 first appears in π at position 104,898 of the decimal expansion (the 104,898ordinal-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.
