Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506846, here are decompositions:

5 + 31506841 = 31506846
17 + 31506829 = 31506846
23 + 31506823 = 31506846
37 + 31506809 = 31506846
47 + 31506799 = 31506846
53 + 31506793 = 31506846
97 + 31506749 = 31506846
103 + 31506743 = 31506846

Showing the first eight; more decompositions exist.
