Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61040, here are decompositions:

  • 13 + 61027 = 61040
  • 79 + 60961 = 61040
  • 97 + 60943 = 61040
  • 103 + 60937 = 61040
  • 127 + 60913 = 61040
  • 139 + 60901 = 61040
  • 151 + 60889 = 61040
  • 181 + 60859 = 61040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61040 first appears in π at position 38,269 of the decimal expansion (the 38,269ordinal-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.
