Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544162, here are decompositions:

31 + 31544131 = 31544162
73 + 31544089 = 31544162
109 + 31544053 = 31544162
151 + 31544011 = 31544162
379 + 31543783 = 31544162
439 + 31543723 = 31544162
619 + 31543543 = 31544162
631 + 31543531 = 31544162

Showing the first eight; more decompositions exist.
