Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40120, here are decompositions:

  • 83 + 40037 = 40120
  • 89 + 40031 = 40120
  • 107 + 40013 = 40120
  • 131 + 39989 = 40120
  • 137 + 39983 = 40120
  • 149 + 39971 = 40120
  • 167 + 39953 = 40120
  • 191 + 39929 = 40120

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40120 first appears in π at position 43,170 of the decimal expansion (the 43,170ordinal-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.
