Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15950, here are decompositions:

  • 13 + 15937 = 15950
  • 31 + 15919 = 15950
  • 37 + 15913 = 15950
  • 43 + 15907 = 15950
  • 61 + 15889 = 15950
  • 73 + 15877 = 15950
  • 127 + 15823 = 15950
  • 163 + 15787 = 15950

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15950 first appears in π at position 46,751 of the decimal expansion (the 46,751ordinal-suffix:st 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.
