Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535822, here are decompositions:

13 + 31535809 = 31535822
151 + 31535671 = 31535822
229 + 31535593 = 31535822
271 + 31535551 = 31535822
691 + 31535131 = 31535822
709 + 31535113 = 31535822
739 + 31535083 = 31535822
811 + 31535011 = 31535822

Showing the first eight; more decompositions exist.
