Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726128, here are decompositions:

  • 41 + 8726087 = 8726128
  • 101 + 8726027 = 8726128
  • 107 + 8726021 = 8726128
  • 137 + 8725991 = 8726128
  • 149 + 8725979 = 8726128
  • 167 + 8725961 = 8726128
  • 179 + 8725949 = 8726128
  • 197 + 8725931 = 8726128

Showing the first eight; more decompositions exist.
