Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488508, here are decompositions:

79 + 2147488429 = 2147488508
97 + 2147488411 = 2147488508
127 + 2147488381 = 2147488508
229 + 2147488279 = 2147488508
337 + 2147488171 = 2147488508
397 + 2147488111 = 2147488508
499 + 2147488009 = 2147488508
577 + 2147487931 = 2147488508

Showing the first eight; more decompositions exist.
