Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489794, here are decompositions:

251 + 2147489543 = 2147489794
257 + 2147489537 = 2147489794
311 + 2147489483 = 2147489794
353 + 2147489441 = 2147489794
503 + 2147489291 = 2147489794
587 + 2147489207 = 2147489794
797 + 2147488997 = 2147489794
881 + 2147488913 = 2147489794

Showing the first eight; more decompositions exist.
