Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458086, here are decompositions:

3 + 31458083 = 31458086
73 + 31458013 = 31458086
97 + 31457989 = 31458086
157 + 31457929 = 31458086
229 + 31457857 = 31458086
349 + 31457737 = 31458086
367 + 31457719 = 31458086
379 + 31457707 = 31458086

Showing the first eight; more decompositions exist.
