Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61356, here are decompositions:

  • 13 + 61343 = 61356
  • 17 + 61339 = 61356
  • 23 + 61333 = 61356
  • 59 + 61297 = 61356
  • 73 + 61283 = 61356
  • 103 + 61253 = 61356
  • 227 + 61129 = 61356
  • 257 + 61099 = 61356

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61356 first appears in π at position 77,992 of the decimal expansion (the 77,992ordinal-suffix:nd 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.
