Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627320, here are decompositions:

17 + 31627303 = 31627320
31 + 31627289 = 31627320
59 + 31627261 = 31627320
71 + 31627249 = 31627320
73 + 31627247 = 31627320
83 + 31627237 = 31627320
103 + 31627217 = 31627320
199 + 31627121 = 31627320

Showing the first eight; more decompositions exist.
