Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608856, here are decompositions:

3 + 31608853 = 31608856
5 + 31608851 = 31608856
107 + 31608749 = 31608856
269 + 31608587 = 31608856
359 + 31608497 = 31608856
593 + 31608263 = 31608856
809 + 31608047 = 31608856
827 + 31608029 = 31608856

Showing the first eight; more decompositions exist.
