Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23290, here are decompositions:

  • 11 + 23279 = 23290
  • 89 + 23201 = 23290
  • 101 + 23189 = 23290
  • 131 + 23159 = 23290
  • 173 + 23117 = 23290
  • 191 + 23099 = 23290
  • 227 + 23063 = 23290
  • 233 + 23057 = 23290

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23290 first appears in π at position 15,782 of the decimal expansion (the 15,782ordinal-suffix:nd 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.
