Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147462378, here are decompositions:

  • 79 + 2147462299 = 2147462378
  • 97 + 2147462281 = 2147462378
  • 151 + 2147462227 = 2147462378
  • 181 + 2147462197 = 2147462378
  • 199 + 2147462179 = 2147462378
  • 331 + 2147462047 = 2147462378
  • 349 + 2147462029 = 2147462378
  • 487 + 2147461891 = 2147462378

Showing the first eight; more decompositions exist.
