Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582, here are decompositions:

41 + 31541 = 31582
71 + 31511 = 31582
101 + 31481 = 31582
113 + 31469 = 31582
191 + 31391 = 31582
263 + 31319 = 31582
311 + 31271 = 31582
359 + 31223 = 31582

Showing the first eight; more decompositions exist.
