Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585082, here are decompositions:

3 + 31585079 = 31585082
181 + 31584901 = 31585082
229 + 31584853 = 31585082
313 + 31584769 = 31585082
379 + 31584703 = 31585082
523 + 31584559 = 31585082
541 + 31584541 = 31585082
601 + 31584481 = 31585082

Showing the first eight; more decompositions exist.
