Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542738, here are decompositions:

  • 11 + 31542727 = 31542738
  • 41 + 31542697 = 31542738
  • 61 + 31542677 = 31542738
  • 79 + 31542659 = 31542738
  • 107 + 31542631 = 31542738
  • 151 + 31542587 = 31542738
  • 179 + 31542559 = 31542738
  • 191 + 31542547 = 31542738

Showing the first eight; more decompositions exist.
