Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938928, here are decompositions:

7 + 938921 = 938928
47 + 938881 = 938928
59 + 938869 = 938928
71 + 938857 = 938928
97 + 938831 = 938928
101 + 938827 = 938928
167 + 938761 = 938928
181 + 938747 = 938928

Showing the first eight; more decompositions exist.
