Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569926, here are decompositions:

43 + 31569883 = 31569926
67 + 31569859 = 31569926
97 + 31569829 = 31569926
163 + 31569763 = 31569926
313 + 31569613 = 31569926
547 + 31569379 = 31569926
607 + 31569319 = 31569926
733 + 31569193 = 31569926

Showing the first eight; more decompositions exist.
