Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444846, here are decompositions:

3 + 31444843 = 31444846
197 + 31444649 = 31444846
443 + 31444403 = 31444846
467 + 31444379 = 31444846
479 + 31444367 = 31444846
599 + 31444247 = 31444846
827 + 31444019 = 31444846
887 + 31443959 = 31444846

Showing the first eight; more decompositions exist.
