Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77180, here are decompositions:

  • 13 + 77167 = 77180
  • 43 + 77137 = 77180
  • 79 + 77101 = 77180
  • 139 + 77041 = 77180
  • 151 + 77029 = 77180
  • 157 + 77023 = 77180
  • 163 + 77017 = 77180
  • 307 + 76873 = 77180

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77180 first appears in π at position 34,808 of the decimal expansion (the 34,808ordinal-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.
