Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493218, here are decompositions:

109 + 2147493109 = 2147493218
139 + 2147493079 = 2147493218
181 + 2147493037 = 2147493218
547 + 2147492671 = 2147493218
691 + 2147492527 = 2147493218
727 + 2147492491 = 2147493218
919 + 2147492299 = 2147493218
1321 + 2147491897 = 2147493218

Showing the first eight; more decompositions exist.
