Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585924, here are decompositions:

101 + 31585823 = 31585924
107 + 31585817 = 31585924
113 + 31585811 = 31585924
173 + 31585751 = 31585924
233 + 31585691 = 31585924
257 + 31585667 = 31585924
311 + 31585613 = 31585924
347 + 31585577 = 31585924

Showing the first eight; more decompositions exist.
