Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458036, here are decompositions:

23 + 31458013 = 31458036
37 + 31457999 = 31458036
47 + 31457989 = 31458036
67 + 31457969 = 31458036
107 + 31457929 = 31458036
167 + 31457869 = 31458036
179 + 31457857 = 31458036
193 + 31457843 = 31458036

Showing the first eight; more decompositions exist.
