Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531622, here are decompositions:

43 + 31531579 = 31531622
139 + 31531483 = 31531622
151 + 31531471 = 31531622
223 + 31531399 = 31531622
349 + 31531273 = 31531622
373 + 31531249 = 31531622
523 + 31531099 = 31531622
643 + 31530979 = 31531622

Showing the first eight; more decompositions exist.
