Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574448, here are decompositions:

5 + 31574443 = 31574448
11 + 31574437 = 31574448
19 + 31574429 = 31574448
29 + 31574419 = 31574448
79 + 31574369 = 31574448
151 + 31574297 = 31574448
317 + 31574131 = 31574448
349 + 31574099 = 31574448

Showing the first eight; more decompositions exist.
