Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536816, here are decompositions:

23 + 31536793 = 31536816
43 + 31536773 = 31536816
83 + 31536733 = 31536816
97 + 31536719 = 31536816
109 + 31536707 = 31536816
277 + 31536539 = 31536816
317 + 31536499 = 31536816
419 + 31536397 = 31536816

Showing the first eight; more decompositions exist.
