Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536008, here are decompositions:

61 + 31535947 = 31536008
67 + 31535941 = 31536008
181 + 31535827 = 31536008
199 + 31535809 = 31536008
211 + 31535797 = 31536008
337 + 31535671 = 31536008
457 + 31535551 = 31536008
541 + 31535467 = 31536008

Showing the first eight; more decompositions exist.
