Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651650, here are decompositions:

  • 3 + 8651647 = 8651650
  • 11 + 8651639 = 8651650
  • 23 + 8651627 = 8651650
  • 41 + 8651609 = 8651650
  • 47 + 8651603 = 8651650
  • 71 + 8651579 = 8651650
  • 101 + 8651549 = 8651650
  • 107 + 8651543 = 8651650

Showing the first eight; more decompositions exist.
