Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461846, here are decompositions:

5 + 31461841 = 31461846
23 + 31461823 = 31461846
29 + 31461817 = 31461846
67 + 31461779 = 31461846
83 + 31461763 = 31461846
103 + 31461743 = 31461846
109 + 31461737 = 31461846
149 + 31461697 = 31461846

Showing the first eight; more decompositions exist.
