Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492678, here are decompositions:

7 + 2147492671 = 2147492678
127 + 2147492551 = 2147492678
139 + 2147492539 = 2147492678
151 + 2147492527 = 2147492678
157 + 2147492521 = 2147492678
307 + 2147492371 = 2147492678
349 + 2147492329 = 2147492678
379 + 2147492299 = 2147492678

Showing the first eight; more decompositions exist.
