Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27556, here are decompositions:

  • 5 + 27551 = 27556
  • 17 + 27539 = 27556
  • 29 + 27527 = 27556
  • 47 + 27509 = 27556
  • 107 + 27449 = 27556
  • 149 + 27407 = 27556
  • 227 + 27329 = 27556
  • 257 + 27299 = 27556

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27556 first appears in π at position 89,090 of the decimal expansion (the 89,090ordinal-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.
