Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520176, here are decompositions:

3 + 31520173 = 31520176
5 + 31520171 = 31520176
59 + 31520117 = 31520176
167 + 31520009 = 31520176
239 + 31519937 = 31520176
257 + 31519919 = 31520176
353 + 31519823 = 31520176
383 + 31519793 = 31520176

Showing the first eight; more decompositions exist.
