Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636490, here are decompositions:

  • 17 + 8636473 = 8636490
  • 41 + 8636449 = 8636490
  • 67 + 8636423 = 8636490
  • 101 + 8636389 = 8636490
  • 103 + 8636387 = 8636490
  • 113 + 8636377 = 8636490
  • 227 + 8636263 = 8636490
  • 229 + 8636261 = 8636490

Showing the first eight; more decompositions exist.
