Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51080, here are decompositions:

  • 19 + 51061 = 51080
  • 37 + 51043 = 51080
  • 79 + 51001 = 51080
  • 109 + 50971 = 51080
  • 151 + 50929 = 51080
  • 157 + 50923 = 51080
  • 223 + 50857 = 51080
  • 241 + 50839 = 51080

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51080 first appears in π at position 148,537 of the decimal expansion (the 148,537ordinal-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.
