Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176890, here are decompositions:

  • 3 + 176887 = 176890
  • 41 + 176849 = 176890
  • 71 + 176819 = 176890
  • 83 + 176807 = 176890
  • 101 + 176789 = 176890
  • 113 + 176777 = 176890
  • 137 + 176753 = 176890
  • 149 + 176741 = 176890

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 176,890 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 176890 first appears in π at position 771,501 of the decimal expansion (the 771,501ordinal-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.
