Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585952, here are decompositions:

103 + 31585849 = 31585952
373 + 31585579 = 31585952
499 + 31585453 = 31585952
613 + 31585339 = 31585952
691 + 31585261 = 31585952
859 + 31585093 = 31585952
919 + 31585033 = 31585952
991 + 31584961 = 31585952

Showing the first eight; more decompositions exist.
