Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997884, here are decompositions:

  • 5 + 997879 = 997884
  • 7 + 997877 = 997884
  • 71 + 997813 = 997884
  • 73 + 997811 = 997884
  • 101 + 997783 = 997884
  • 157 + 997727 = 997884
  • 191 + 997693 = 997884
  • 233 + 997651 = 997884

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 997,884 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 997884 first appears in π at position 345,601 of the decimal expansion (the 345,601ordinal-suffix:st 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.
