Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627488, here are decompositions:

5 + 31627483 = 31627488
97 + 31627391 = 31627488
131 + 31627357 = 31627488
199 + 31627289 = 31627488
227 + 31627261 = 31627488
239 + 31627249 = 31627488
241 + 31627247 = 31627488
251 + 31627237 = 31627488

Showing the first eight; more decompositions exist.
