Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582010, here are decompositions:

7 + 31582003 = 31582010
13 + 31581997 = 31582010
37 + 31581973 = 31582010
127 + 31581883 = 31582010
151 + 31581859 = 31582010
193 + 31581817 = 31582010
223 + 31581787 = 31582010
331 + 31581679 = 31582010

Showing the first eight; more decompositions exist.
