Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485240, here are decompositions:

59 + 2147485181 = 2147485240
107 + 2147485133 = 2147485240
167 + 2147485073 = 2147485240
311 + 2147484929 = 2147485240
389 + 2147484851 = 2147485240
419 + 2147484821 = 2147485240
449 + 2147484791 = 2147485240
599 + 2147484641 = 2147485240

Showing the first eight; more decompositions exist.
