Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31050, here are decompositions:

  • 11 + 31039 = 31050
  • 17 + 31033 = 31050
  • 31 + 31019 = 31050
  • 37 + 31013 = 31050
  • 67 + 30983 = 31050
  • 73 + 30977 = 31050
  • 79 + 30971 = 31050
  • 101 + 30949 = 31050

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31050 first appears in π at position 34,728 of the decimal expansion (the 34,728ordinal-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.
