Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726178, here are decompositions:

  • 37 + 8726141 = 8726178
  • 127 + 8726051 = 8726178
  • 151 + 8726027 = 8726178
  • 157 + 8726021 = 8726178
  • 179 + 8725999 = 8726178
  • 191 + 8725987 = 8726178
  • 199 + 8725979 = 8726178
  • 229 + 8725949 = 8726178

Showing the first eight; more decompositions exist.
