Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582182, here are decompositions:

11 + 31582171 = 31582182
19 + 31582163 = 31582182
61 + 31582121 = 31582182
89 + 31582093 = 31582182
139 + 31582043 = 31582182
179 + 31582003 = 31582182
199 + 31581983 = 31582182
271 + 31581911 = 31582182

Showing the first eight; more decompositions exist.
