Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520336, here are decompositions:

19 + 31520317 = 31520336
37 + 31520299 = 31520336
103 + 31520233 = 31520336
157 + 31520179 = 31520336
163 + 31520173 = 31520336
277 + 31520059 = 31520336
307 + 31520029 = 31520336
349 + 31519987 = 31520336

Showing the first eight; more decompositions exist.
