Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45180, here are decompositions:

  • 19 + 45161 = 45180
  • 41 + 45139 = 45180
  • 43 + 45137 = 45180
  • 53 + 45127 = 45180
  • 59 + 45121 = 45180
  • 61 + 45119 = 45180
  • 97 + 45083 = 45180
  • 103 + 45077 = 45180

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45180 first appears in π at position 46,286 of the decimal expansion (the 46,286ordinal-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.
