Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534818, here are decompositions:

17 + 31534801 = 31534818
19 + 31534799 = 31534818
31 + 31534787 = 31534818
61 + 31534757 = 31534818
67 + 31534751 = 31534818
79 + 31534739 = 31534818
89 + 31534729 = 31534818
109 + 31534709 = 31534818

Showing the first eight; more decompositions exist.
