Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627570, here are decompositions:

3 + 31627567 = 31627570
11 + 31627559 = 31627570
59 + 31627511 = 31627570
179 + 31627391 = 31627570
197 + 31627373 = 31627570
251 + 31627319 = 31627570
281 + 31627289 = 31627570
353 + 31627217 = 31627570

Showing the first eight; more decompositions exist.
