Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582312, here are decompositions:

71 + 31582241 = 31582312
149 + 31582163 = 31582312
191 + 31582121 = 31582312
263 + 31582049 = 31582312
269 + 31582043 = 31582312
401 + 31581911 = 31582312
431 + 31581881 = 31582312
449 + 31581863 = 31582312

Showing the first eight; more decompositions exist.
