Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444926, here are decompositions:

47 + 31444879 = 31444926
83 + 31444843 = 31444926
89 + 31444837 = 31444926
113 + 31444813 = 31444926
137 + 31444789 = 31444926
167 + 31444759 = 31444926
199 + 31444727 = 31444926
277 + 31444649 = 31444926

Showing the first eight; more decompositions exist.
