Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189288, here are decompositions:

  • 17 + 189271 = 189288
  • 31 + 189257 = 189288
  • 37 + 189251 = 189288
  • 59 + 189229 = 189288
  • 89 + 189199 = 189288
  • 101 + 189187 = 189288
  • 137 + 189151 = 189288
  • 139 + 189149 = 189288

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 189,288 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 189288 first appears in π at position 59,407 of the decimal expansion (the 59,407ordinal-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.
