Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612642, here are decompositions:

  • 13 + 8612629 = 8612642
  • 61 + 8612581 = 8612642
  • 139 + 8612503 = 8612642
  • 163 + 8612479 = 8612642
  • 229 + 8612413 = 8612642
  • 331 + 8612311 = 8612642
  • 349 + 8612293 = 8612642
  • 421 + 8612221 = 8612642

Showing the first eight; more decompositions exist.
