Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544330, here are decompositions:

7 + 31544323 = 31544330
19 + 31544311 = 31544330
109 + 31544221 = 31544330
151 + 31544179 = 31544330
163 + 31544167 = 31544330
199 + 31544131 = 31544330
241 + 31544089 = 31544330
277 + 31544053 = 31544330

Showing the first eight; more decompositions exist.
