Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627308, here are decompositions:

5 + 31627303 = 31627308
19 + 31627289 = 31627308
47 + 31627261 = 31627308
59 + 31627249 = 31627308
61 + 31627247 = 31627308
71 + 31627237 = 31627308
107 + 31627201 = 31627308
157 + 31627151 = 31627308

Showing the first eight; more decompositions exist.
