Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494332, here are decompositions:

31 + 31494301 = 31494332
241 + 31494091 = 31494332
349 + 31493983 = 31494332
433 + 31493899 = 31494332
643 + 31493689 = 31494332
691 + 31493641 = 31494332
733 + 31493599 = 31494332
739 + 31493593 = 31494332

Showing the first eight; more decompositions exist.
