Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84390, here are decompositions:

  • 13 + 84377 = 84390
  • 41 + 84349 = 84390
  • 43 + 84347 = 84390
  • 71 + 84319 = 84390
  • 73 + 84317 = 84390
  • 83 + 84307 = 84390
  • 127 + 84263 = 84390
  • 151 + 84239 = 84390

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 84390 first appears in π at position 2,300 of the decimal expansion (the 2,300ordinal-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.
