Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469770, here are decompositions:

67 + 2147469703 = 2147469770
151 + 2147469619 = 2147469770
307 + 2147469463 = 2147469770
349 + 2147469421 = 2147469770
487 + 2147469283 = 2147469770
499 + 2147469271 = 2147469770
541 + 2147469229 = 2147469770
613 + 2147469157 = 2147469770

Showing the first eight; more decompositions exist.
