Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582682, here are decompositions:

3 + 31582679 = 31582682
73 + 31582609 = 31582682
151 + 31582531 = 31582682
193 + 31582489 = 31582682
211 + 31582471 = 31582682
283 + 31582399 = 31582682
349 + 31582333 = 31582682
433 + 31582249 = 31582682

Showing the first eight; more decompositions exist.
