Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536992, here are decompositions:

163 + 31536829 = 31536992
199 + 31536793 = 31536992
379 + 31536613 = 31536992
463 + 31536529 = 31536992
601 + 31536391 = 31536992
631 + 31536361 = 31536992
769 + 31536223 = 31536992
1009 + 31535983 = 31536992

Showing the first eight; more decompositions exist.
