Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466880, here are decompositions:

  • 11 + 2147466869 = 2147466880
  • 47 + 2147466833 = 2147466880
  • 179 + 2147466701 = 2147466880
  • 197 + 2147466683 = 2147466880
  • 239 + 2147466641 = 2147466880
  • 359 + 2147466521 = 2147466880
  • 401 + 2147466479 = 2147466880
  • 431 + 2147466449 = 2147466880

Showing the first eight; more decompositions exist.
