Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628618, here are decompositions:

  • 17 + 8628601 = 8628618
  • 67 + 8628551 = 8628618
  • 71 + 8628547 = 8628618
  • 137 + 8628481 = 8628618
  • 139 + 8628479 = 8628618
  • 197 + 8628421 = 8628618
  • 211 + 8628407 = 8628618
  • 241 + 8628377 = 8628618

Showing the first eight; more decompositions exist.
