Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51136, here are decompositions:

  • 3 + 51133 = 51136
  • 5 + 51131 = 51136
  • 89 + 51047 = 51136
  • 167 + 50969 = 51136
  • 179 + 50957 = 51136
  • 227 + 50909 = 51136
  • 263 + 50873 = 51136
  • 269 + 50867 = 51136

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51136 first appears in π at position 92,424 of the decimal expansion (the 92,424ordinal-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.
