Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462566, here are decompositions:

13 + 31462553 = 31462566
19 + 31462547 = 31462566
59 + 31462507 = 31462566
127 + 31462439 = 31462566
193 + 31462373 = 31462566
227 + 31462339 = 31462566
277 + 31462289 = 31462566
293 + 31462273 = 31462566

Showing the first eight; more decompositions exist.
