Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672740, here are decompositions:

  • 17 + 8672723 = 8672740
  • 53 + 8672687 = 8672740
  • 101 + 8672639 = 8672740
  • 179 + 8672561 = 8672740
  • 227 + 8672513 = 8672740
  • 239 + 8672501 = 8672740
  • 257 + 8672483 = 8672740
  • 269 + 8672471 = 8672740

Showing the first eight; more decompositions exist.
