Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541448, here are decompositions:

11 + 31541437 = 31541448
19 + 31541429 = 31541448
31 + 31541417 = 31541448
47 + 31541401 = 31541448
89 + 31541359 = 31541448
101 + 31541347 = 31541448
151 + 31541297 = 31541448
167 + 31541281 = 31541448

Showing the first eight; more decompositions exist.
