Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585954, here are decompositions:

17 + 31585937 = 31585954
131 + 31585823 = 31585954
137 + 31585817 = 31585954
173 + 31585781 = 31585954
263 + 31585691 = 31585954
317 + 31585637 = 31585954
383 + 31585571 = 31585954
461 + 31585493 = 31585954

Showing the first eight; more decompositions exist.
