Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582252, here are decompositions:

3 + 31582249 = 31582252
11 + 31582241 = 31582252
59 + 31582193 = 31582252
89 + 31582163 = 31582252
131 + 31582121 = 31582252
269 + 31581983 = 31582252
389 + 31581863 = 31582252
491 + 31581761 = 31582252

Showing the first eight; more decompositions exist.
