Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25736, here are decompositions:

  • 3 + 25733 = 25736
  • 19 + 25717 = 25736
  • 43 + 25693 = 25736
  • 79 + 25657 = 25736
  • 97 + 25639 = 25736
  • 103 + 25633 = 25736
  • 127 + 25609 = 25736
  • 157 + 25579 = 25736

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25736 first appears in π at position 74,780 of the decimal expansion (the 74,780ordinal-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.
