Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544504, here are decompositions:

157 + 31544347 = 31544504
181 + 31544323 = 31544504
193 + 31544311 = 31544504
223 + 31544281 = 31544504
283 + 31544221 = 31544504
337 + 31544167 = 31544504
373 + 31544131 = 31544504
463 + 31544041 = 31544504

Showing the first eight; more decompositions exist.
