Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536976, here are decompositions:

17 + 31536959 = 31536976
59 + 31536917 = 31536976
113 + 31536863 = 31536976
257 + 31536719 = 31536976
269 + 31536707 = 31536976
347 + 31536629 = 31536976
593 + 31536383 = 31536976
617 + 31536359 = 31536976

Showing the first eight; more decompositions exist.
