Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404178, here are decompositions:

37 + 2147404141 = 2147404178
79 + 2147404099 = 2147404178
397 + 2147403781 = 2147404178
631 + 2147403547 = 2147404178
709 + 2147403469 = 2147404178
769 + 2147403409 = 2147404178
1117 + 2147403061 = 2147404178
1171 + 2147403007 = 2147404178

Showing the first eight; more decompositions exist.
