Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404846, here are decompositions:

5 + 2147404841 = 2147404846
17 + 2147404829 = 2147404846
227 + 2147404619 = 2147404846
263 + 2147404583 = 2147404846
269 + 2147404577 = 2147404846
599 + 2147404247 = 2147404846
617 + 2147404229 = 2147404846
809 + 2147404037 = 2147404846

Showing the first eight; more decompositions exist.
