Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486866, here are decompositions:

17 + 2147486849 = 2147486866
23 + 2147486843 = 2147486866
47 + 2147486819 = 2147486866
197 + 2147486669 = 2147486866
353 + 2147486513 = 2147486866
359 + 2147486507 = 2147486866
443 + 2147486423 = 2147486866
467 + 2147486399 = 2147486866

Showing the first eight; more decompositions exist.
