Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494662, here are decompositions:

19 + 31494643 = 31494662
79 + 31494583 = 31494662
109 + 31494553 = 31494662
193 + 31494469 = 31494662
223 + 31494439 = 31494662
421 + 31494241 = 31494662
571 + 31494091 = 31494662
673 + 31493989 = 31494662

Showing the first eight; more decompositions exist.
