Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25584, here are decompositions:

  • 5 + 25579 = 25584
  • 7 + 25577 = 25584
  • 23 + 25561 = 25584
  • 43 + 25541 = 25584
  • 47 + 25537 = 25584
  • 61 + 25523 = 25584
  • 113 + 25471 = 25584
  • 127 + 25457 = 25584

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25584 first appears in π at position 179,942 of the decimal expansion (the 179,942ordinal-suffix:nd 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.
