Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536012, here are decompositions:

29 + 31535983 = 31536012
31 + 31535981 = 31536012
71 + 31535941 = 31536012
73 + 31535939 = 31536012
103 + 31535909 = 31536012
181 + 31535831 = 31536012
191 + 31535821 = 31536012
271 + 31535741 = 31536012

Showing the first eight; more decompositions exist.
