Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998540, here are decompositions:

  • 3 + 998537 = 998540
  • 13 + 998527 = 998540
  • 43 + 998497 = 998540
  • 97 + 998443 = 998540
  • 163 + 998377 = 998540
  • 211 + 998329 = 998540
  • 229 + 998311 = 998540
  • 373 + 998167 = 998540

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 998,540 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 998540 first appears in π at position 101,910 of the decimal expansion (the 101,910ordinal-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.
