Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494146, here are decompositions:

3 + 31494143 = 31494146
67 + 31494079 = 31494146
157 + 31493989 = 31494146
163 + 31493983 = 31494146
367 + 31493779 = 31494146
457 + 31493689 = 31494146
547 + 31493599 = 31494146
577 + 31493569 = 31494146

Showing the first eight; more decompositions exist.
