Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637186, here are decompositions:

  • 7 + 8637179 = 8637186
  • 23 + 8637163 = 8637186
  • 53 + 8637133 = 8637186
  • 67 + 8637119 = 8637186
  • 79 + 8637107 = 8637186
  • 83 + 8637103 = 8637186
  • 127 + 8637059 = 8637186
  • 179 + 8637007 = 8637186

Showing the first eight; more decompositions exist.
