Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28524, here are decompositions:

  • 7 + 28517 = 28524
  • 11 + 28513 = 28524
  • 31 + 28493 = 28524
  • 47 + 28477 = 28524
  • 61 + 28463 = 28524
  • 113 + 28411 = 28524
  • 131 + 28393 = 28524
  • 137 + 28387 = 28524

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28524 first appears in π at position 24,456 of the decimal expansion (the 24,456ordinal-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.
