Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494602, here are decompositions:

19 + 31494583 = 31494602
163 + 31494439 = 31494602
523 + 31494079 = 31494602
613 + 31493989 = 31494602
619 + 31493983 = 31494602
661 + 31493941 = 31494602
751 + 31493851 = 31494602
823 + 31493779 = 31494602

Showing the first eight; more decompositions exist.
