Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642382, here are decompositions:

  • 53 + 8642329 = 8642382
  • 79 + 8642303 = 8642382
  • 101 + 8642281 = 8642382
  • 193 + 8642189 = 8642382
  • 223 + 8642159 = 8642382
  • 241 + 8642141 = 8642382
  • 263 + 8642119 = 8642382
  • 271 + 8642111 = 8642382

Showing the first eight; more decompositions exist.
