Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627266, here are decompositions:

5 + 31627261 = 31627266
17 + 31627249 = 31627266
19 + 31627247 = 31627266
23 + 31627243 = 31627266
29 + 31627237 = 31627266
193 + 31627073 = 31627266
197 + 31627069 = 31627266
233 + 31627033 = 31627266

Showing the first eight; more decompositions exist.
