Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544358, here are decompositions:

11 + 31544347 = 31544358
47 + 31544311 = 31544358
61 + 31544297 = 31544358
137 + 31544221 = 31544358
151 + 31544207 = 31544358
179 + 31544179 = 31544358
191 + 31544167 = 31544358
227 + 31544131 = 31544358

Showing the first eight; more decompositions exist.
