Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567470, here are decompositions:

19 + 31567451 = 31567470
41 + 31567429 = 31567470
43 + 31567427 = 31567470
59 + 31567411 = 31567470
73 + 31567397 = 31567470
101 + 31567369 = 31567470
157 + 31567313 = 31567470
173 + 31567297 = 31567470

Showing the first eight; more decompositions exist.
