Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613638, here are decompositions:

  • 67 + 8613571 = 8613638
  • 79 + 8613559 = 8613638
  • 109 + 8613529 = 8613638
  • 157 + 8613481 = 8613638
  • 181 + 8613457 = 8613638
  • 199 + 8613439 = 8613638
  • 211 + 8613427 = 8613638
  • 409 + 8613229 = 8613638

Showing the first eight; more decompositions exist.
