Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189012, here are decompositions:

  • 13 + 188999 = 189012
  • 29 + 188983 = 189012
  • 59 + 188953 = 189012
  • 71 + 188941 = 189012
  • 73 + 188939 = 189012
  • 79 + 188933 = 189012
  • 101 + 188911 = 189012
  • 149 + 188863 = 189012

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 189,012 and was likely granted around 1875.

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

Position in π

The digit sequence 189012 first appears in π at position 398,656 of the decimal expansion (the 398,656ordinal-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.
