Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189308, here are decompositions:

  • 37 + 189271 = 189308
  • 79 + 189229 = 189308
  • 109 + 189199 = 189308
  • 139 + 189169 = 189308
  • 157 + 189151 = 189308
  • 181 + 189127 = 189308
  • 241 + 189067 = 189308
  • 367 + 188941 = 189308

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 189,308 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 189308 first appears in π at position 184,197 of the decimal expansion (the 184,197ordinal-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.
