Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486056, here are decompositions:

23 + 31486033 = 31486056
47 + 31486009 = 31486056
83 + 31485973 = 31486056
97 + 31485959 = 31486056
103 + 31485953 = 31486056
139 + 31485917 = 31486056
163 + 31485893 = 31486056
167 + 31485889 = 31486056

Showing the first eight; more decompositions exist.
