Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038888, here are decompositions:

7 + 1038881 = 1038888
61 + 1038827 = 1038888
131 + 1038757 = 1038888
157 + 1038731 = 1038888
167 + 1038721 = 1038888
181 + 1038707 = 1038888
197 + 1038691 = 1038888
199 + 1038689 = 1038888

Showing the first eight; more decompositions exist.
