Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584572, here are decompositions:

13 + 31584559 = 31584572
31 + 31584541 = 31584572
73 + 31584499 = 31584572
199 + 31584373 = 31584572
211 + 31584361 = 31584572
379 + 31584193 = 31584572
433 + 31584139 = 31584572
601 + 31583971 = 31584572

Showing the first eight; more decompositions exist.
