Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688992, here are decompositions:

  • 31 + 8688961 = 8688992
  • 73 + 8688919 = 8688992
  • 163 + 8688829 = 8688992
  • 379 + 8688613 = 8688992
  • 409 + 8688583 = 8688992
  • 421 + 8688571 = 8688992
  • 439 + 8688553 = 8688992
  • 523 + 8688469 = 8688992

Showing the first eight; more decompositions exist.
