Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444996, here are decompositions:

3 + 31444993 = 31444996
59 + 31444937 = 31444996
269 + 31444727 = 31444996
347 + 31444649 = 31444996
353 + 31444643 = 31444996
449 + 31444547 = 31444996
593 + 31444403 = 31444996
617 + 31444379 = 31444996

Showing the first eight; more decompositions exist.
