Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494476, here are decompositions:

7 + 31494469 = 31494476
37 + 31494439 = 31494476
229 + 31494247 = 31494476
379 + 31494097 = 31494476
397 + 31494079 = 31494476
487 + 31493989 = 31494476
577 + 31493899 = 31494476
619 + 31493857 = 31494476

Showing the first eight; more decompositions exist.
