Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544324, here are decompositions:

13 + 31544311 = 31544324
43 + 31544281 = 31544324
103 + 31544221 = 31544324
157 + 31544167 = 31544324
193 + 31544131 = 31544324
271 + 31544053 = 31544324
283 + 31544041 = 31544324
313 + 31544011 = 31544324

Showing the first eight; more decompositions exist.
