Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625618, here are decompositions:

  • 19 + 8625599 = 8625618
  • 31 + 8625587 = 8625618
  • 59 + 8625559 = 8625618
  • 97 + 8625521 = 8625618
  • 101 + 8625517 = 8625618
  • 109 + 8625509 = 8625618
  • 139 + 8625479 = 8625618
  • 151 + 8625467 = 8625618

Showing the first eight; more decompositions exist.
