Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534822, here are decompositions:

3 + 31534819 = 31534822
23 + 31534799 = 31534822
71 + 31534751 = 31534822
83 + 31534739 = 31534822
113 + 31534709 = 31534822
131 + 31534691 = 31534822
191 + 31534631 = 31534822
233 + 31534589 = 31534822

Showing the first eight; more decompositions exist.
