Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544364, here are decompositions:

17 + 31544347 = 31544364
41 + 31544323 = 31544364
53 + 31544311 = 31544364
67 + 31544297 = 31544364
83 + 31544281 = 31544364
151 + 31544213 = 31544364
157 + 31544207 = 31544364
193 + 31544171 = 31544364

Showing the first eight; more decompositions exist.
