Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627310, here are decompositions:

7 + 31627303 = 31627310
61 + 31627249 = 31627310
67 + 31627243 = 31627310
73 + 31627237 = 31627310
109 + 31627201 = 31627310
241 + 31627069 = 31627310
277 + 31627033 = 31627310
283 + 31627027 = 31627310

Showing the first eight; more decompositions exist.
