Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19574, here are decompositions:

  • 3 + 19571 = 19574
  • 31 + 19543 = 19574
  • 43 + 19531 = 19574
  • 67 + 19507 = 19574
  • 73 + 19501 = 19574
  • 97 + 19477 = 19574
  • 103 + 19471 = 19574
  • 127 + 19447 = 19574

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19574 first appears in π at position 49,004 of the decimal expansion (the 49,004ordinal-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.
