Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582952, here are decompositions:

3 + 31582949 = 31582952
61 + 31582891 = 31582952
223 + 31582729 = 31582952
421 + 31582531 = 31582952
439 + 31582513 = 31582952
463 + 31582489 = 31582952
619 + 31582333 = 31582952
631 + 31582321 = 31582952

Showing the first eight; more decompositions exist.
