Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608462, here are decompositions:

13 + 31608449 = 31608462
113 + 31608349 = 31608462
191 + 31608271 = 31608462
199 + 31608263 = 31608462
293 + 31608169 = 31608462
313 + 31608149 = 31608462
331 + 31608131 = 31608462
401 + 31608061 = 31608462

Showing the first eight; more decompositions exist.
