Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162980, here are decompositions:

  • 7 + 162973 = 162980
  • 43 + 162937 = 162980
  • 73 + 162907 = 162980
  • 79 + 162901 = 162980
  • 127 + 162853 = 162980
  • 151 + 162829 = 162980
  • 157 + 162823 = 162980
  • 193 + 162787 = 162980

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 162,980 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 162980 first appears in π at position 315,850 of the decimal expansion (the 315,850ordinal-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.
