Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487976, here are decompositions:

107 + 2147487869 = 2147487976
149 + 2147487827 = 2147487976
173 + 2147487803 = 2147487976
197 + 2147487779 = 2147487976
353 + 2147487623 = 2147487976
467 + 2147487509 = 2147487976
503 + 2147487473 = 2147487976
617 + 2147487359 = 2147487976

Showing the first eight; more decompositions exist.
