Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488244, here are decompositions:

73 + 2147488171 = 2147488244
313 + 2147487931 = 2147488244
337 + 2147487907 = 2147488244
373 + 2147487871 = 2147488244
463 + 2147487781 = 2147488244
487 + 2147487757 = 2147488244
541 + 2147487703 = 2147488244
607 + 2147487637 = 2147488244

Showing the first eight; more decompositions exist.
