Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457022, here are decompositions:

13 + 31457009 = 31457022
73 + 31456949 = 31457022
131 + 31456891 = 31457022
139 + 31456883 = 31457022
173 + 31456849 = 31457022
193 + 31456829 = 31457022
241 + 31456781 = 31457022
281 + 31456741 = 31457022

Showing the first eight; more decompositions exist.
