Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584502, here are decompositions:

3 + 31584499 = 31584502
71 + 31584431 = 31584502
101 + 31584401 = 31584502
113 + 31584389 = 31584502
179 + 31584323 = 31584502
239 + 31584263 = 31584502
269 + 31584233 = 31584502
311 + 31584191 = 31584502

Showing the first eight; more decompositions exist.
