Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672890, here are decompositions:

  • 29 + 8672861 = 8672890
  • 59 + 8672831 = 8672890
  • 71 + 8672819 = 8672890
  • 89 + 8672801 = 8672890
  • 101 + 8672789 = 8672890
  • 167 + 8672723 = 8672890
  • 251 + 8672639 = 8672890
  • 269 + 8672621 = 8672890

Showing the first eight; more decompositions exist.
