Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25850, here are decompositions:

  • 3 + 25847 = 25850
  • 31 + 25819 = 25850
  • 79 + 25771 = 25850
  • 103 + 25747 = 25850
  • 109 + 25741 = 25850
  • 157 + 25693 = 25850
  • 193 + 25657 = 25850
  • 211 + 25639 = 25850

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25850 first appears in π at position 205,039 of the decimal expansion (the 205,039ordinal-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.
