Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520350, here are decompositions:

11 + 31520339 = 31520350
41 + 31520309 = 31520350
107 + 31520243 = 31520350
149 + 31520201 = 31520350
179 + 31520171 = 31520350
233 + 31520117 = 31520350
431 + 31519919 = 31520350
461 + 31519889 = 31520350

Showing the first eight; more decompositions exist.
