Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544312, here are decompositions:

31 + 31544281 = 31544312
181 + 31544131 = 31544312
223 + 31544089 = 31544312
271 + 31544041 = 31544312
409 + 31543903 = 31544312
439 + 31543873 = 31544312
601 + 31543711 = 31544312
643 + 31543669 = 31544312

Showing the first eight; more decompositions exist.
