Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997970, here are decompositions:

  • 7 + 997963 = 997970
  • 37 + 997933 = 997970
  • 73 + 997897 = 997970
  • 79 + 997891 = 997970
  • 157 + 997813 = 997970
  • 163 + 997807 = 997970
  • 229 + 997741 = 997970
  • 271 + 997699 = 997970

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 997,970 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 997970 first appears in π at position 126,237 of the decimal expansion (the 126,237ordinal-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.
