Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444932, here are decompositions:

31 + 31444901 = 31444932
41 + 31444891 = 31444932
53 + 31444879 = 31444932
61 + 31444871 = 31444932
89 + 31444843 = 31444932
131 + 31444801 = 31444932
173 + 31444759 = 31444932
241 + 31444691 = 31444932

Showing the first eight; more decompositions exist.
