Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30492, here are decompositions:

  • 23 + 30469 = 30492
  • 43 + 30449 = 30492
  • 61 + 30431 = 30492
  • 89 + 30403 = 30492
  • 101 + 30391 = 30492
  • 103 + 30389 = 30492
  • 151 + 30341 = 30492
  • 173 + 30319 = 30492

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30492 first appears in π at position 124,879 of the decimal expansion (the 124,879ordinal-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.
