Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672858, here are decompositions:

  • 37 + 8672821 = 8672858
  • 67 + 8672791 = 8672858
  • 79 + 8672779 = 8672858
  • 127 + 8672731 = 8672858
  • 151 + 8672707 = 8672858
  • 199 + 8672659 = 8672858
  • 211 + 8672647 = 8672858
  • 307 + 8672551 = 8672858

Showing the first eight; more decompositions exist.
