Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627622, here are decompositions:

79 + 31627543 = 31627622
139 + 31627483 = 31627622
211 + 31627411 = 31627622
373 + 31627249 = 31627622
379 + 31627243 = 31627622
421 + 31627201 = 31627622
571 + 31627051 = 31627622
643 + 31626979 = 31627622

Showing the first eight; more decompositions exist.
