Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189378, here are decompositions:

  • 17 + 189361 = 189378
  • 29 + 189349 = 189378
  • 31 + 189347 = 189378
  • 41 + 189337 = 189378
  • 67 + 189311 = 189378
  • 71 + 189307 = 189378
  • 107 + 189271 = 189378
  • 127 + 189251 = 189378

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 189,378 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 189378 first appears in π at position 709,864 of the decimal expansion (the 709,864ordinal-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.
