Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488820, here are decompositions:

  • 79 + 2147488741 = 2147488820
  • 241 + 2147488579 = 2147488820
  • 277 + 2147488543 = 2147488820
  • 409 + 2147488411 = 2147488820
  • 439 + 2147488381 = 2147488820
  • 487 + 2147488333 = 2147488820
  • 541 + 2147488279 = 2147488820
  • 571 + 2147488249 = 2147488820

Showing the first eight; more decompositions exist.
