Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616240, here are decompositions:

  • 19 + 8616221 = 8616240
  • 23 + 8616217 = 8616240
  • 37 + 8616203 = 8616240
  • 41 + 8616199 = 8616240
  • 43 + 8616197 = 8616240
  • 53 + 8616187 = 8616240
  • 67 + 8616173 = 8616240
  • 71 + 8616169 = 8616240

Showing the first eight; more decompositions exist.
