Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30658, here are decompositions:

  • 101 + 30557 = 30658
  • 149 + 30509 = 30658
  • 167 + 30491 = 30658
  • 191 + 30467 = 30658
  • 227 + 30431 = 30658
  • 269 + 30389 = 30658
  • 311 + 30347 = 30658
  • 317 + 30341 = 30658

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30658 first appears in π at position 13,875 of the decimal expansion (the 13,875ordinal-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.
