Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582112, here are decompositions:

19 + 31582093 = 31582112
109 + 31582003 = 31582112
139 + 31581973 = 31582112
151 + 31581961 = 31582112
223 + 31581889 = 31582112
229 + 31581883 = 31582112
433 + 31581679 = 31582112
439 + 31581673 = 31582112

Showing the first eight; more decompositions exist.
