Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576650, here are decompositions:

  • 11 + 31576639 = 31576650
  • 31 + 31576619 = 31576650
  • 67 + 31576583 = 31576650
  • 71 + 31576579 = 31576650
  • 101 + 31576549 = 31576650
  • 109 + 31576541 = 31576650
  • 139 + 31576511 = 31576650
  • 167 + 31576483 = 31576650

Showing the first eight; more decompositions exist.
