Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738942, here are decompositions:

13 + 8738929 = 8738942
61 + 8738881 = 8738942
103 + 8738839 = 8738942
229 + 8738713 = 8738942
271 + 8738671 = 8738942
283 + 8738659 = 8738942
409 + 8738533 = 8738942
643 + 8738299 = 8738942

Showing the first eight; more decompositions exist.
