Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585054, here are decompositions:

101 + 31584953 = 31585054
107 + 31584947 = 31585054
167 + 31584887 = 31585054
173 + 31584881 = 31585054
257 + 31584797 = 31585054
401 + 31584653 = 31585054
503 + 31584551 = 31585054
647 + 31584407 = 31585054

Showing the first eight; more decompositions exist.
