Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567610, here are decompositions:

7 + 31567603 = 31567610
97 + 31567513 = 31567610
181 + 31567429 = 31567610
199 + 31567411 = 31567610
241 + 31567369 = 31567610
313 + 31567297 = 31567610
331 + 31567279 = 31567610
379 + 31567231 = 31567610

Showing the first eight; more decompositions exist.
