Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27730, here are decompositions:

  • 29 + 27701 = 27730
  • 41 + 27689 = 27730
  • 83 + 27647 = 27730
  • 113 + 27617 = 27730
  • 149 + 27581 = 27730
  • 179 + 27551 = 27730
  • 191 + 27539 = 27730
  • 251 + 27479 = 27730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27730 first appears in π at position 138,758 of the decimal expansion (the 138,758ordinal-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.
