Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665390, here are decompositions:

  • 17 + 8665373 = 8665390
  • 29 + 8665361 = 8665390
  • 113 + 8665277 = 8665390
  • 131 + 8665259 = 8665390
  • 137 + 8665253 = 8665390
  • 197 + 8665193 = 8665390
  • 233 + 8665157 = 8665390
  • 281 + 8665109 = 8665390

Showing the first eight; more decompositions exist.
