Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25854, here are decompositions:

  • 5 + 25849 = 25854
  • 7 + 25847 = 25854
  • 13 + 25841 = 25854
  • 53 + 25801 = 25854
  • 61 + 25793 = 25854
  • 83 + 25771 = 25854
  • 107 + 25747 = 25854
  • 113 + 25741 = 25854

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25854 first appears in π at position 83,783 of the decimal expansion (the 83,783ordinal-suffix:rd 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.
