Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486974, here are decompositions:

5 + 2147486969 = 2147486974
47 + 2147486927 = 2147486974
131 + 2147486843 = 2147486974
233 + 2147486741 = 2147486974
263 + 2147486711 = 2147486974
443 + 2147486531 = 2147486974
461 + 2147486513 = 2147486974
467 + 2147486507 = 2147486974

Showing the first eight; more decompositions exist.
