Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147520202, here are decompositions:

  • 173 + 2147520029 = 2147520202
  • 263 + 2147519939 = 2147520202
  • 293 + 2147519909 = 2147520202
  • 389 + 2147519813 = 2147520202
  • 521 + 2147519681 = 2147520202
  • 593 + 2147519609 = 2147520202
  • 719 + 2147519483 = 2147520202
  • 809 + 2147519393 = 2147520202

Showing the first eight; more decompositions exist.
