Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627482, here are decompositions:

71 + 31627411 = 31627482
109 + 31627373 = 31627482
149 + 31627333 = 31627482
163 + 31627319 = 31627482
179 + 31627303 = 31627482
193 + 31627289 = 31627482
233 + 31627249 = 31627482
239 + 31627243 = 31627482

Showing the first eight; more decompositions exist.
