Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493158, here are decompositions:

79 + 2147493079 = 2147493158
157 + 2147493001 = 2147493158
199 + 2147492959 = 2147493158
229 + 2147492929 = 2147493158
457 + 2147492701 = 2147493158
487 + 2147492671 = 2147493158
607 + 2147492551 = 2147493158
619 + 2147492539 = 2147493158

Showing the first eight; more decompositions exist.
