Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047278, here are decompositions:

7 + 1047271 = 1047278
31 + 1047247 = 1047278
79 + 1047199 = 1047278
139 + 1047139 = 1047278
151 + 1047127 = 1047278
181 + 1047097 = 1047278
487 + 1046791 = 1047278
499 + 1046779 = 1047278

Showing the first eight; more decompositions exist.
