Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27570, here are decompositions:

  • 19 + 27551 = 27570
  • 29 + 27541 = 27570
  • 31 + 27539 = 27570
  • 41 + 27529 = 27570
  • 43 + 27527 = 27570
  • 61 + 27509 = 27570
  • 83 + 27487 = 27570
  • 89 + 27481 = 27570

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27570 first appears in π at position 58,333 of the decimal expansion (the 58,333ordinal-suffix:rd 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.
