Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544326, here are decompositions:

3 + 31544323 = 31544326
29 + 31544297 = 31544326
113 + 31544213 = 31544326
137 + 31544189 = 31544326
173 + 31544153 = 31544326
227 + 31544099 = 31544326
269 + 31544057 = 31544326
293 + 31544033 = 31544326

Showing the first eight; more decompositions exist.
