Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444954, here are decompositions:

17 + 31444937 = 31444954
53 + 31444901 = 31444954
83 + 31444871 = 31444954
227 + 31444727 = 31444954
263 + 31444691 = 31444954
293 + 31444661 = 31444954
311 + 31444643 = 31444954
587 + 31444367 = 31444954

Showing the first eight; more decompositions exist.
