Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544226, here are decompositions:

5 + 31544221 = 31544226
13 + 31544213 = 31544226
19 + 31544207 = 31544226
37 + 31544189 = 31544226
47 + 31544179 = 31544226
59 + 31544167 = 31544226
73 + 31544153 = 31544226
127 + 31544099 = 31544226

Showing the first eight; more decompositions exist.
