Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469992, here are decompositions:

  • 43 + 2147469949 = 2147469992
  • 163 + 2147469829 = 2147469992
  • 211 + 2147469781 = 2147469992
  • 313 + 2147469679 = 2147469992
  • 373 + 2147469619 = 2147469992
  • 439 + 2147469553 = 2147469992
  • 571 + 2147469421 = 2147469992
  • 709 + 2147469283 = 2147469992

Showing the first eight; more decompositions exist.
