Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40424, here are decompositions:

  • 37 + 40387 = 40424
  • 67 + 40357 = 40424
  • 73 + 40351 = 40424
  • 193 + 40231 = 40424
  • 211 + 40213 = 40424
  • 271 + 40153 = 40424
  • 313 + 40111 = 40424
  • 331 + 40093 = 40424

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40424 first appears in π at position 70,028 of the decimal expansion (the 70,028ordinal-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.
