Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468252, here are decompositions:

  • 3 + 2147468249 = 2147468252
  • 19 + 2147468233 = 2147468252
  • 79 + 2147468173 = 2147468252
  • 331 + 2147467921 = 2147468252
  • 439 + 2147467813 = 2147468252
  • 541 + 2147467711 = 2147468252
  • 613 + 2147467639 = 2147468252
  • 673 + 2147467579 = 2147468252

Showing the first eight; more decompositions exist.
