Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627356, here are decompositions:

23 + 31627333 = 31627356
37 + 31627319 = 31627356
53 + 31627303 = 31627356
67 + 31627289 = 31627356
107 + 31627249 = 31627356
109 + 31627247 = 31627356
113 + 31627243 = 31627356
139 + 31627217 = 31627356

Showing the first eight; more decompositions exist.
