Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999312, here are decompositions:

  • 5 + 999307 = 999312
  • 43 + 999269 = 999312
  • 73 + 999239 = 999312
  • 79 + 999233 = 999312
  • 113 + 999199 = 999312
  • 131 + 999181 = 999312
  • 163 + 999149 = 999312
  • 179 + 999133 = 999312

Showing the first eight; more decompositions exist.
