Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585814, here are decompositions:

3 + 31585811 = 31585814
31 + 31585783 = 31585814
37 + 31585777 = 31585814
151 + 31585663 = 31585814
277 + 31585537 = 31585814
313 + 31585501 = 31585814
367 + 31585447 = 31585814
373 + 31585441 = 31585814

Showing the first eight; more decompositions exist.
