Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444966, here are decompositions:

29 + 31444937 = 31444966
89 + 31444877 = 31444966
239 + 31444727 = 31444966
317 + 31444649 = 31444966
419 + 31444547 = 31444966
563 + 31444403 = 31444966
587 + 31444379 = 31444966
599 + 31444367 = 31444966

Showing the first eight; more decompositions exist.
