Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476320, here are decompositions:

3 + 31476317 = 31476320
37 + 31476283 = 31476320
151 + 31476169 = 31476320
163 + 31476157 = 31476320
223 + 31476097 = 31476320
307 + 31476013 = 31476320
367 + 31475953 = 31476320
409 + 31475911 = 31476320

Showing the first eight; more decompositions exist.
