Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61250, here are decompositions:

  • 19 + 61231 = 61250
  • 97 + 61153 = 61250
  • 109 + 61141 = 61250
  • 151 + 61099 = 61250
  • 193 + 61057 = 61250
  • 199 + 61051 = 61250
  • 223 + 61027 = 61250
  • 307 + 60943 = 61250

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61250 first appears in π at position 501,136 of the decimal expansion (the 501,136ordinal-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.
