Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585132, here are decompositions:

53 + 31585079 = 31585132
71 + 31585061 = 31585132
113 + 31585019 = 31585132
179 + 31584953 = 31585132
251 + 31584881 = 31585132
263 + 31584869 = 31585132
419 + 31584713 = 31585132
443 + 31584689 = 31585132

Showing the first eight; more decompositions exist.
