Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535846, here are decompositions:

19 + 31535827 = 31535846
37 + 31535809 = 31535846
379 + 31535467 = 31535846
613 + 31535233 = 31535846
619 + 31535227 = 31535846
673 + 31535173 = 31535846
733 + 31535113 = 31535846
739 + 31535107 = 31535846

Showing the first eight; more decompositions exist.
