Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569026, here are decompositions:

109 + 31568917 = 31569026
157 + 31568869 = 31569026
193 + 31568833 = 31569026
199 + 31568827 = 31569026
277 + 31568749 = 31569026
283 + 31568743 = 31569026
397 + 31568629 = 31569026
439 + 31568587 = 31569026

Showing the first eight; more decompositions exist.
