Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670618, here are decompositions:

  • 7 + 8670611 = 8670618
  • 29 + 8670589 = 8670618
  • 59 + 8670559 = 8670618
  • 67 + 8670551 = 8670618
  • 109 + 8670509 = 8670618
  • 127 + 8670491 = 8670618
  • 137 + 8670481 = 8670618
  • 167 + 8670451 = 8670618

Showing the first eight; more decompositions exist.
