Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567574, here are decompositions:

61 + 31567513 = 31567574
163 + 31567411 = 31567574
277 + 31567297 = 31567574
307 + 31567267 = 31567574
421 + 31567153 = 31567574
487 + 31567087 = 31567574
601 + 31566973 = 31567574
607 + 31566967 = 31567574

Showing the first eight; more decompositions exist.
