Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15610, here are decompositions:

  • 3 + 15607 = 15610
  • 29 + 15581 = 15610
  • 41 + 15569 = 15610
  • 59 + 15551 = 15610
  • 83 + 15527 = 15610
  • 113 + 15497 = 15610
  • 137 + 15473 = 15610
  • 149 + 15461 = 15610

Showing the first eight; more decompositions exist.
