Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458226, here are decompositions:

29 + 31458197 = 31458226
53 + 31458173 = 31458226
113 + 31458113 = 31458226
227 + 31457999 = 31458226
257 + 31457969 = 31458226
383 + 31457843 = 31458226
467 + 31457759 = 31458226
509 + 31457717 = 31458226

Showing the first eight; more decompositions exist.
