Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444882, here are decompositions:

3 + 31444879 = 31444882
5 + 31444877 = 31444882
11 + 31444871 = 31444882
191 + 31444691 = 31444882
233 + 31444649 = 31444882
239 + 31444643 = 31444882
251 + 31444631 = 31444882
479 + 31444403 = 31444882

Showing the first eight; more decompositions exist.
