Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147460818, here are decompositions:

  • 7 + 2147460811 = 2147460818
  • 37 + 2147460781 = 2147460818
  • 109 + 2147460709 = 2147460818
  • 229 + 2147460589 = 2147460818
  • 271 + 2147460547 = 2147460818
  • 397 + 2147460421 = 2147460818
  • 439 + 2147460379 = 2147460818
  • 541 + 2147460277 = 2147460818

Showing the first eight; more decompositions exist.
