Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454448, here are decompositions:

7 + 31454441 = 31454448
17 + 31454431 = 31454448
59 + 31454389 = 31454448
71 + 31454377 = 31454448
97 + 31454351 = 31454448
127 + 31454321 = 31454448
199 + 31454249 = 31454448
227 + 31454221 = 31454448

Showing the first eight; more decompositions exist.
