Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444974, here are decompositions:

37 + 31444937 = 31444974
73 + 31444901 = 31444974
83 + 31444891 = 31444974
97 + 31444877 = 31444974
103 + 31444871 = 31444974
131 + 31444843 = 31444974
137 + 31444837 = 31444974
167 + 31444807 = 31444974

Showing the first eight; more decompositions exist.
