Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757442, here are decompositions:

  • 53 + 8757389 = 8757442
  • 101 + 8757341 = 8757442
  • 173 + 8757269 = 8757442
  • 179 + 8757263 = 8757442
  • 233 + 8757209 = 8757442
  • 251 + 8757191 = 8757442
  • 263 + 8757179 = 8757442
  • 269 + 8757173 = 8757442

Showing the first eight; more decompositions exist.
