Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494434, here are decompositions:

3 + 31494431 = 31494434
7 + 31494427 = 31494434
193 + 31494241 = 31494434
277 + 31494157 = 31494434
337 + 31494097 = 31494434
577 + 31493857 = 31494434
613 + 31493821 = 31494434
691 + 31493743 = 31494434

Showing the first eight; more decompositions exist.
