Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494848, here are decompositions:

31 + 31494817 = 31494848
67 + 31494781 = 31494848
79 + 31494769 = 31494848
127 + 31494721 = 31494848
157 + 31494691 = 31494848
211 + 31494637 = 31494848
379 + 31494469 = 31494848
409 + 31494439 = 31494848

Showing the first eight; more decompositions exist.
