Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444696, here are decompositions:

5 + 31444691 = 31444696
47 + 31444649 = 31444696
53 + 31444643 = 31444696
137 + 31444559 = 31444696
149 + 31444547 = 31444696
293 + 31444403 = 31444696
317 + 31444379 = 31444696
383 + 31444313 = 31444696

Showing the first eight; more decompositions exist.
