Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038218, here are decompositions:

7 + 1038211 = 1038218
19 + 1038199 = 1038218
31 + 1038187 = 1038218
61 + 1038157 = 1038218
199 + 1038019 = 1038218
277 + 1037941 = 1038218
541 + 1037677 = 1038218
607 + 1037611 = 1038218

Showing the first eight; more decompositions exist.
