Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668188, here are decompositions:

  • 31 + 8668157 = 8668188
  • 37 + 8668151 = 8668188
  • 47 + 8668141 = 8668188
  • 107 + 8668081 = 8668188
  • 127 + 8668061 = 8668188
  • 131 + 8668057 = 8668188
  • 157 + 8668031 = 8668188
  • 227 + 8667961 = 8668188

Showing the first eight; more decompositions exist.
