Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585982, here are decompositions:

3 + 31585979 = 31585982
19 + 31585963 = 31585982
79 + 31585903 = 31585982
199 + 31585783 = 31585982
433 + 31585549 = 31585982
523 + 31585459 = 31585982
541 + 31585441 = 31585982
613 + 31585369 = 31585982

Showing the first eight; more decompositions exist.
