Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749572, here are decompositions:

  • 23 + 8749549 = 8749572
  • 103 + 8749469 = 8749572
  • 149 + 8749423 = 8749572
  • 151 + 8749421 = 8749572
  • 229 + 8749343 = 8749572
  • 241 + 8749331 = 8749572
  • 263 + 8749309 = 8749572
  • 353 + 8749219 = 8749572

Showing the first eight; more decompositions exist.
