Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159970, here are decompositions:

  • 59 + 159911 = 159970
  • 71 + 159899 = 159970
  • 101 + 159869 = 159970
  • 113 + 159857 = 159970
  • 131 + 159839 = 159970
  • 137 + 159833 = 159970
  • 179 + 159791 = 159970
  • 191 + 159779 = 159970

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 159,970 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 159970 first appears in π at position 406,129 of the decimal expansion (the 406,129ordinal-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.
