Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160906, here are decompositions:

  • 3 + 160903 = 160906
  • 23 + 160883 = 160906
  • 29 + 160877 = 160906
  • 89 + 160817 = 160906
  • 149 + 160757 = 160906
  • 167 + 160739 = 160906
  • 197 + 160709 = 160906
  • 257 + 160649 = 160906

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 160,906 and was likely granted around 1874.

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

Position in π

The digit sequence 160906 first appears in π at position 561,612 of the decimal expansion (the 561,612ordinal-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.
