Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637122, here are decompositions:

  • 3 + 8637119 = 8637122
  • 19 + 8637103 = 8637122
  • 31 + 8637091 = 8637122
  • 61 + 8637061 = 8637122
  • 163 + 8636959 = 8637122
  • 199 + 8636923 = 8637122
  • 211 + 8636911 = 8637122
  • 223 + 8636899 = 8637122

Showing the first eight; more decompositions exist.
