Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638554, here are decompositions:

  • 11 + 8638543 = 8638554
  • 37 + 8638517 = 8638554
  • 73 + 8638481 = 8638554
  • 83 + 8638471 = 8638554
  • 97 + 8638457 = 8638554
  • 101 + 8638453 = 8638554
  • 103 + 8638451 = 8638554
  • 107 + 8638447 = 8638554

Showing the first eight; more decompositions exist.
