Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615952, here are decompositions:

31 + 31615921 = 31615952
61 + 31615891 = 31615952
103 + 31615849 = 31615952
211 + 31615741 = 31615952
223 + 31615729 = 31615952
241 + 31615711 = 31615952
283 + 31615669 = 31615952
349 + 31615603 = 31615952

Showing the first eight; more decompositions exist.
