Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541750, here are decompositions:

  • 13 + 31541737 = 31541750
  • 43 + 31541707 = 31541750
  • 73 + 31541677 = 31541750
  • 139 + 31541611 = 31541750
  • 181 + 31541569 = 31541750
  • 193 + 31541557 = 31541750
  • 223 + 31541527 = 31541750
  • 241 + 31541509 = 31541750

Showing the first eight; more decompositions exist.
