Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493578, here are decompositions:

31 + 2147493547 = 2147493578
277 + 2147493301 = 2147493578
337 + 2147493241 = 2147493578
409 + 2147493169 = 2147493578
499 + 2147493079 = 2147493578
541 + 2147493037 = 2147493578
577 + 2147493001 = 2147493578
619 + 2147492959 = 2147493578

Showing the first eight; more decompositions exist.
