Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544212, here are decompositions:

5 + 31544207 = 31544212
23 + 31544189 = 31544212
41 + 31544171 = 31544212
59 + 31544153 = 31544212
113 + 31544099 = 31544212
173 + 31544039 = 31544212
179 + 31544033 = 31544212
191 + 31544021 = 31544212

Showing the first eight; more decompositions exist.
