Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672136, here are decompositions:

  • 19 + 8672117 = 8672136
  • 37 + 8672099 = 8672136
  • 73 + 8672063 = 8672136
  • 89 + 8672047 = 8672136
  • 149 + 8671987 = 8672136
  • 157 + 8671979 = 8672136
  • 199 + 8671937 = 8672136
  • 229 + 8671907 = 8672136

Showing the first eight; more decompositions exist.
