Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494226, here are decompositions:

47 + 31494179 = 31494226
83 + 31494143 = 31494226
107 + 31494119 = 31494226
173 + 31494053 = 31494226
227 + 31493999 = 31494226
317 + 31493909 = 31494226
443 + 31493783 = 31494226
509 + 31493717 = 31494226

Showing the first eight; more decompositions exist.
