Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569996, here are decompositions:

13 + 31569983 = 31569996
19 + 31569977 = 31569996
43 + 31569953 = 31569996
53 + 31569943 = 31569996
113 + 31569883 = 31569996
137 + 31569859 = 31569996
167 + 31569829 = 31569996
229 + 31569767 = 31569996

Showing the first eight; more decompositions exist.
