Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477778, here are decompositions:

41 + 2147477737 = 2147477778
79 + 2147477699 = 2147477778
97 + 2147477681 = 2147477778
151 + 2147477627 = 2147477778
179 + 2147477599 = 2147477778
311 + 2147477467 = 2147477778
359 + 2147477419 = 2147477778
379 + 2147477399 = 2147477778

Showing the first eight; more decompositions exist.
