Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536822, here are decompositions:

29 + 31536793 = 31536822
89 + 31536733 = 31536822
103 + 31536719 = 31536822
193 + 31536629 = 31536822
271 + 31536551 = 31536822
283 + 31536539 = 31536822
293 + 31536529 = 31536822
419 + 31536403 = 31536822

Showing the first eight; more decompositions exist.
