Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567608, here are decompositions:

5 + 31567603 = 31567608
97 + 31567511 = 31567608
157 + 31567451 = 31567608
179 + 31567429 = 31567608
181 + 31567427 = 31567608
197 + 31567411 = 31567608
211 + 31567397 = 31567608
239 + 31567369 = 31567608

Showing the first eight; more decompositions exist.
