Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585922, here are decompositions:

19 + 31585903 = 31585922
73 + 31585849 = 31585922
139 + 31585783 = 31585922
373 + 31585549 = 31585922
421 + 31585501 = 31585922
463 + 31585459 = 31585922
523 + 31585399 = 31585922
661 + 31585261 = 31585922

Showing the first eight; more decompositions exist.
