Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488390, here are decompositions:

83 + 2147488307 = 2147488390
227 + 2147488163 = 2147488390
239 + 2147488151 = 2147488390
347 + 2147488043 = 2147488390
389 + 2147488001 = 2147488390
449 + 2147487941 = 2147488390
491 + 2147487899 = 2147488390
521 + 2147487869 = 2147488390

Showing the first eight; more decompositions exist.
