Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645162, here are decompositions:

  • 109 + 8645053 = 8645162
  • 139 + 8645023 = 8645162
  • 151 + 8645011 = 8645162
  • 199 + 8644963 = 8645162
  • 433 + 8644729 = 8645162
  • 439 + 8644723 = 8645162
  • 661 + 8644501 = 8645162
  • 709 + 8644453 = 8645162

Showing the first eight; more decompositions exist.
