Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544164, here are decompositions:

11 + 31544153 = 31544164
107 + 31544057 = 31544164
131 + 31544033 = 31544164
167 + 31543997 = 31544164
173 + 31543991 = 31544164
251 + 31543913 = 31544164
257 + 31543907 = 31544164
293 + 31543871 = 31544164

Showing the first eight; more decompositions exist.
