Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997904, here are decompositions:

  • 7 + 997897 = 997904
  • 13 + 997891 = 997904
  • 97 + 997807 = 997904
  • 163 + 997741 = 997904
  • 211 + 997693 = 997904
  • 223 + 997681 = 997904
  • 241 + 997663 = 997904
  • 277 + 997627 = 997904

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 997,904 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 997904 first appears in π at position 143,093 of the decimal expansion (the 143,093ordinal-suffix:rd 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.
