Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610448, here are decompositions:

11 + 31610437 = 31610448
59 + 31610389 = 31610448
109 + 31610339 = 31610448
131 + 31610317 = 31610448
157 + 31610291 = 31610448
179 + 31610269 = 31610448
211 + 31610237 = 31610448
251 + 31610197 = 31610448

Showing the first eight; more decompositions exist.
