Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444888, here are decompositions:

11 + 31444877 = 31444888
17 + 31444871 = 31444888
197 + 31444691 = 31444888
227 + 31444661 = 31444888
239 + 31444649 = 31444888
257 + 31444631 = 31444888
347 + 31444541 = 31444888
509 + 31444379 = 31444888

Showing the first eight; more decompositions exist.
