Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15090, here are decompositions:

  • 7 + 15083 = 15090
  • 13 + 15077 = 15090
  • 17 + 15073 = 15090
  • 29 + 15061 = 15090
  • 37 + 15053 = 15090
  • 59 + 15031 = 15090
  • 73 + 15017 = 15090
  • 107 + 14983 = 15090

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15090 first appears in π at position 575,876 of the decimal expansion (the 575,876ordinal-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.
