Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047218, here are decompositions:

19 + 1047199 = 1047218
61 + 1047157 = 1047218
79 + 1047139 = 1047218
157 + 1047061 = 1047218
241 + 1046977 = 1047218
421 + 1046797 = 1047218
439 + 1046779 = 1047218
541 + 1046677 = 1047218

Showing the first eight; more decompositions exist.
