Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544228, here are decompositions:

7 + 31544221 = 31544228
61 + 31544167 = 31544228
97 + 31544131 = 31544228
139 + 31544089 = 31544228
151 + 31544077 = 31544228
241 + 31543987 = 31544228
739 + 31543489 = 31544228
997 + 31543231 = 31544228

Showing the first eight; more decompositions exist.
