Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461946, here are decompositions:

3 + 31461943 = 31461946
23 + 31461923 = 31461946
53 + 31461893 = 31461946
59 + 31461887 = 31461946
167 + 31461779 = 31461946
293 + 31461653 = 31461946
389 + 31461557 = 31461946
653 + 31461293 = 31461946

Showing the first eight; more decompositions exist.
