Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657436, here are decompositions:

  • 5 + 8657431 = 8657436
  • 13 + 8657423 = 8657436
  • 59 + 8657377 = 8657436
  • 79 + 8657357 = 8657436
  • 103 + 8657333 = 8657436
  • 113 + 8657323 = 8657436
  • 127 + 8657309 = 8657436
  • 197 + 8657239 = 8657436

Showing the first eight; more decompositions exist.
