Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489634, here are decompositions:

223 + 31489411 = 31489634
271 + 31489363 = 31489634
457 + 31489177 = 31489634
487 + 31489147 = 31489634
571 + 31489063 = 31489634
607 + 31489027 = 31489634
643 + 31488991 = 31489634
727 + 31488907 = 31489634

Showing the first eight; more decompositions exist.
