Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998758, here are decompositions:

  • 41 + 998717 = 998758
  • 71 + 998687 = 998758
  • 107 + 998651 = 998758
  • 197 + 998561 = 998758
  • 347 + 998411 = 998758
  • 359 + 998399 = 998758
  • 521 + 998237 = 998758
  • 557 + 998201 = 998758

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 998,758 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 998758 first appears in π at position 22,765 of the decimal expansion (the 22,765ordinal-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.
