Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494626, here are decompositions:

43 + 31494583 = 31494626
73 + 31494553 = 31494626
157 + 31494469 = 31494626
199 + 31494427 = 31494626
379 + 31494247 = 31494626
547 + 31494079 = 31494626
643 + 31493983 = 31494626
727 + 31493899 = 31494626

Showing the first eight; more decompositions exist.
