Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147494628, here are decompositions:

271 + 2147494357 = 2147494628
397 + 2147494231 = 2147494628
421 + 2147494207 = 2147494628
541 + 2147494087 = 2147494628
607 + 2147494021 = 2147494628
691 + 2147493937 = 2147494628
709 + 2147493919 = 2147494628
739 + 2147493889 = 2147494628

Showing the first eight; more decompositions exist.
