Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493386, here are decompositions:

97 + 2147493289 = 2147493386
109 + 2147493277 = 2147493386
277 + 2147493109 = 2147493386
307 + 2147493079 = 2147493386
349 + 2147493037 = 2147493386
457 + 2147492929 = 2147493386
463 + 2147492923 = 2147493386
733 + 2147492653 = 2147493386

Showing the first eight; more decompositions exist.
