Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477044, here are decompositions:

17 + 31477027 = 31477044
23 + 31477021 = 31477044
97 + 31476947 = 31477044
113 + 31476931 = 31477044
127 + 31476917 = 31477044
163 + 31476881 = 31477044
173 + 31476871 = 31477044
191 + 31476853 = 31477044

Showing the first eight; more decompositions exist.
