Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468870, here are decompositions:

  • 37 + 2147468833 = 2147468870
  • 61 + 2147468809 = 2147468870
  • 67 + 2147468803 = 2147468870
  • 97 + 2147468773 = 2147468870
  • 271 + 2147468599 = 2147468870
  • 307 + 2147468563 = 2147468870
  • 367 + 2147468503 = 2147468870
  • 373 + 2147468497 = 2147468870

Showing the first eight; more decompositions exist.
