Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61128, here are decompositions:

  • 7 + 61121 = 61128
  • 29 + 61099 = 61128
  • 37 + 61091 = 61128
  • 71 + 61057 = 61128
  • 97 + 61031 = 61128
  • 101 + 61027 = 61128
  • 127 + 61001 = 61128
  • 167 + 60961 = 61128

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61128 first appears in π at position 14,717 of the decimal expansion (the 14,717ordinal-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.
