Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582132, here are decompositions:

11 + 31582121 = 31582132
83 + 31582049 = 31582132
89 + 31582043 = 31582132
149 + 31581983 = 31582132
251 + 31581881 = 31582132
269 + 31581863 = 31582132
353 + 31581779 = 31582132
401 + 31581731 = 31582132

Showing the first eight; more decompositions exist.
