Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30378, here are decompositions:

  • 11 + 30367 = 30378
  • 31 + 30347 = 30378
  • 37 + 30341 = 30378
  • 59 + 30319 = 30378
  • 71 + 30307 = 30378
  • 107 + 30271 = 30378
  • 109 + 30269 = 30378
  • 137 + 30241 = 30378

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30378 first appears in π at position 100,158 of the decimal expansion (the 100,158ordinal-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.
