Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516552, here are decompositions:

29 + 31516523 = 31516552
59 + 31516493 = 31516552
83 + 31516469 = 31516552
173 + 31516379 = 31516552
191 + 31516361 = 31516552
233 + 31516319 = 31516552
311 + 31516241 = 31516552
443 + 31516109 = 31516552

Showing the first eight; more decompositions exist.
