Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500840, here are decompositions:

  • 59 + 2147500781 = 2147500840
  • 179 + 2147500661 = 2147500840
  • 227 + 2147500613 = 2147500840
  • 281 + 2147500559 = 2147500840
  • 347 + 2147500493 = 2147500840
  • 479 + 2147500361 = 2147500840
  • 593 + 2147500247 = 2147500840
  • 599 + 2147500241 = 2147500840

Showing the first eight; more decompositions exist.
