Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627606, here are decompositions:

5 + 31627601 = 31627606
29 + 31627577 = 31627606
47 + 31627559 = 31627606
233 + 31627373 = 31627606
317 + 31627289 = 31627606
359 + 31627247 = 31627606
389 + 31627217 = 31627606
599 + 31627007 = 31627606

Showing the first eight; more decompositions exist.
