Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40156, here are decompositions:

  • 3 + 40153 = 40156
  • 5 + 40151 = 40156
  • 29 + 40127 = 40156
  • 167 + 39989 = 40156
  • 173 + 39983 = 40156
  • 227 + 39929 = 40156
  • 269 + 39887 = 40156
  • 293 + 39863 = 40156

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40156 first appears in π at position 56,489 of the decimal expansion (the 56,489ordinal-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.
