Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444776, here are decompositions:

5 + 31444771 = 31444776
17 + 31444759 = 31444776
53 + 31444723 = 31444776
59 + 31444717 = 31444776
127 + 31444649 = 31444776
149 + 31444627 = 31444776
229 + 31444547 = 31444776
239 + 31444537 = 31444776

Showing the first eight; more decompositions exist.
