Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535996, here are decompositions:

13 + 31535983 = 31535996
199 + 31535797 = 31535996
577 + 31535419 = 31535996
619 + 31535377 = 31535996
733 + 31535263 = 31535996
769 + 31535227 = 31535996
823 + 31535173 = 31535996
853 + 31535143 = 31535996

Showing the first eight; more decompositions exist.
