Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30458, here are decompositions:

  • 31 + 30427 = 30458
  • 67 + 30391 = 30458
  • 139 + 30319 = 30458
  • 151 + 30307 = 30458
  • 199 + 30259 = 30458
  • 271 + 30187 = 30458
  • 277 + 30181 = 30458
  • 349 + 30109 = 30458

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30458 first appears in π at position 105,896 of the decimal expansion (the 105,896ordinal-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.
