Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486466, here are decompositions:

3 + 31486463 = 31486466
13 + 31486453 = 31486466
43 + 31486423 = 31486466
73 + 31486393 = 31486466
79 + 31486387 = 31486466
127 + 31486339 = 31486466
139 + 31486327 = 31486466
163 + 31486303 = 31486466

Showing the first eight; more decompositions exist.
