Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461822, here are decompositions:

5 + 31461817 = 31461822
11 + 31461811 = 31461822
31 + 31461791 = 31461822
43 + 31461779 = 31461822
59 + 31461763 = 31461822
61 + 31461761 = 31461822
79 + 31461743 = 31461822
149 + 31461673 = 31461822

Showing the first eight; more decompositions exist.
