Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61100, here are decompositions:

  • 43 + 61057 = 61100
  • 73 + 61027 = 61100
  • 139 + 60961 = 61100
  • 157 + 60943 = 61100
  • 163 + 60937 = 61100
  • 181 + 60919 = 61100
  • 199 + 60901 = 61100
  • 211 + 60889 = 61100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61100 first appears in π at position 200,697 of the decimal expansion (the 200,697ordinal-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.
