Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458326, here are decompositions:

139 + 31458187 = 31458326
157 + 31458169 = 31458326
313 + 31458013 = 31458326
337 + 31457989 = 31458326
397 + 31457929 = 31458326
457 + 31457869 = 31458326
607 + 31457719 = 31458326
619 + 31457707 = 31458326

Showing the first eight; more decompositions exist.
