Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147401802, here are decompositions:

  • 43 + 2147401759 = 2147401802
  • 61 + 2147401741 = 2147401802
  • 211 + 2147401591 = 2147401802
  • 229 + 2147401573 = 2147401802
  • 433 + 2147401369 = 2147401802
  • 499 + 2147401303 = 2147401802
  • 631 + 2147401171 = 2147401802
  • 673 + 2147401129 = 2147401802

Showing the first eight; more decompositions exist.
