Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472832, here are decompositions:

  • 149 + 2147472683 = 2147472832
  • 173 + 2147472659 = 2147472832
  • 383 + 2147472449 = 2147472832
  • 389 + 2147472443 = 2147472832
  • 419 + 2147472413 = 2147472832
  • 521 + 2147472311 = 2147472832
  • 569 + 2147472263 = 2147472832
  • 761 + 2147472071 = 2147472832

Showing the first eight; more decompositions exist.
