Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490218, here are decompositions:

109 + 2147490109 = 2147490218
157 + 2147490061 = 2147490218
271 + 2147489947 = 2147490218
277 + 2147489941 = 2147490218
397 + 2147489821 = 2147490218
421 + 2147489797 = 2147490218
631 + 2147489587 = 2147490218
919 + 2147489299 = 2147490218

Showing the first eight; more decompositions exist.
