Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609982, here are decompositions:

163 + 31609819 = 31609982
223 + 31609759 = 31609982
241 + 31609741 = 31609982
373 + 31609609 = 31609982
421 + 31609561 = 31609982
433 + 31609549 = 31609982
463 + 31609519 = 31609982
601 + 31609381 = 31609982

Showing the first eight; more decompositions exist.
