Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494448, here are decompositions:

5 + 31494443 = 31494448
17 + 31494431 = 31494448
47 + 31494401 = 31494448
59 + 31494389 = 31494448
101 + 31494347 = 31494448
191 + 31494257 = 31494448
269 + 31494179 = 31494448
449 + 31493999 = 31494448

Showing the first eight; more decompositions exist.
