Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444982, here are decompositions:

43 + 31444939 = 31444982
103 + 31444879 = 31444982
139 + 31444843 = 31444982
181 + 31444801 = 31444982
193 + 31444789 = 31444982
211 + 31444771 = 31444982
223 + 31444759 = 31444982
409 + 31444573 = 31444982

Showing the first eight; more decompositions exist.
