Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997930, here are decompositions:

  • 41 + 997889 = 997930
  • 53 + 997877 = 997930
  • 137 + 997793 = 997930
  • 179 + 997751 = 997930
  • 191 + 997739 = 997930
  • 281 + 997649 = 997930
  • 293 + 997637 = 997930
  • 347 + 997583 = 997930

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 997,930 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 997930 first appears in π at position 438,392 of the decimal expansion (the 438,392ordinal-suffix:nd 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.
