Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147424902, here are decompositions:

  • 3 + 2147424899 = 2147424902
  • 109 + 2147424793 = 2147424902
  • 193 + 2147424709 = 2147424902
  • 313 + 2147424589 = 2147424902
  • 379 + 2147424523 = 2147424902
  • 421 + 2147424481 = 2147424902
  • 433 + 2147424469 = 2147424902
  • 643 + 2147424259 = 2147424902

Showing the first eight; more decompositions exist.
