Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485820, here are decompositions:

  • 3 + 2147485817 = 2147485820
  • 13 + 2147485807 = 2147485820
  • 61 + 2147485759 = 2147485820
  • 229 + 2147485591 = 2147485820
  • 373 + 2147485447 = 2147485820
  • 397 + 2147485423 = 2147485820
  • 409 + 2147485411 = 2147485820
  • 439 + 2147485381 = 2147485820

Showing the first eight; more decompositions exist.
