Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582282, here are decompositions:

41 + 31582241 = 31582282
89 + 31582193 = 31582282
233 + 31582049 = 31582282
239 + 31582043 = 31582282
401 + 31581881 = 31582282
419 + 31581863 = 31582282
503 + 31581779 = 31582282
521 + 31581761 = 31582282

Showing the first eight; more decompositions exist.
