Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520334, here are decompositions:

17 + 31520317 = 31520334
101 + 31520233 = 31520334
163 + 31520171 = 31520334
193 + 31520141 = 31520334
317 + 31520017 = 31520334
347 + 31519987 = 31520334
383 + 31519951 = 31520334
397 + 31519937 = 31520334

Showing the first eight; more decompositions exist.
