Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467448, here are decompositions:

11 + 31467437 = 31467448
17 + 31467431 = 31467448
29 + 31467419 = 31467448
59 + 31467389 = 31467448
101 + 31467347 = 31467448
137 + 31467311 = 31467448
197 + 31467251 = 31467448
281 + 31467167 = 31467448

Showing the first eight; more decompositions exist.
