Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458026, here are decompositions:

13 + 31458013 = 31458026
37 + 31457989 = 31458026
97 + 31457929 = 31458026
157 + 31457869 = 31458026
283 + 31457743 = 31458026
307 + 31457719 = 31458026
547 + 31457479 = 31458026
577 + 31457449 = 31458026

Showing the first eight; more decompositions exist.
