Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462556, here are decompositions:

3 + 31462553 = 31462556
193 + 31462363 = 31462556
199 + 31462357 = 31462556
283 + 31462273 = 31462556
487 + 31462069 = 31462556
577 + 31461979 = 31462556
607 + 31461949 = 31462556
613 + 31461943 = 31462556

Showing the first eight; more decompositions exist.
