Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536662, here are decompositions:

163 + 31536499 = 31536662
181 + 31536481 = 31536662
271 + 31536391 = 31536662
349 + 31536313 = 31536662
439 + 31536223 = 31536662
601 + 31536061 = 31536662
613 + 31536049 = 31536662
643 + 31536019 = 31536662

Showing the first eight; more decompositions exist.
