Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147494730, here are decompositions:

67 + 2147494663 = 2147494730
127 + 2147494603 = 2147494730
193 + 2147494537 = 2147494730
223 + 2147494507 = 2147494730
373 + 2147494357 = 2147494730
457 + 2147494273 = 2147494730
463 + 2147494267 = 2147494730
499 + 2147494231 = 2147494730

Showing the first eight; more decompositions exist.
