Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147424844, here are decompositions:

  • 17 + 2147424827 = 2147424844
  • 281 + 2147424563 = 2147424844
  • 293 + 2147424551 = 2147424844
  • 311 + 2147424533 = 2147424844
  • 491 + 2147424353 = 2147424844
  • 557 + 2147424287 = 2147424844
  • 641 + 2147424203 = 2147424844
  • 701 + 2147424143 = 2147424844

Showing the first eight; more decompositions exist.
