Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665240, here are decompositions:

  • 47 + 8665193 = 8665240
  • 83 + 8665157 = 8665240
  • 131 + 8665109 = 8665240
  • 167 + 8665073 = 8665240
  • 263 + 8664977 = 8665240
  • 281 + 8664959 = 8665240
  • 293 + 8664947 = 8665240
  • 383 + 8664857 = 8665240

Showing the first eight; more decompositions exist.
