Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569104, here are decompositions:

13 + 31569091 = 31569104
31 + 31569073 = 31569104
67 + 31569037 = 31569104
271 + 31568833 = 31569104
277 + 31568827 = 31569104
337 + 31568767 = 31569104
367 + 31568737 = 31569104
577 + 31568527 = 31569104

Showing the first eight; more decompositions exist.
