Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997958, here are decompositions:

  • 61 + 997897 = 997958
  • 67 + 997891 = 997958
  • 79 + 997879 = 997958
  • 151 + 997807 = 997958
  • 277 + 997681 = 997958
  • 307 + 997651 = 997958
  • 331 + 997627 = 997958
  • 349 + 997609 = 997958

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 997,958 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 997958 first appears in π at position 360,250 of the decimal expansion (the 360,250ordinal-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.
