Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687282, here are decompositions:

  • 73 + 8687209 = 8687282
  • 151 + 8687131 = 8687282
  • 193 + 8687089 = 8687282
  • 283 + 8686999 = 8687282
  • 613 + 8686669 = 8687282
  • 631 + 8686651 = 8687282
  • 811 + 8686471 = 8687282
  • 823 + 8686459 = 8687282

Showing the first eight; more decompositions exist.
