Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539182, here are decompositions:

19 + 31539163 = 31539182
109 + 31539073 = 31539182
139 + 31539043 = 31539182
439 + 31538743 = 31539182
463 + 31538719 = 31539182
541 + 31538641 = 31539182
601 + 31538581 = 31539182
613 + 31538569 = 31539182

Showing the first eight; more decompositions exist.
