Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536042, here are decompositions:

23 + 31536019 = 31536042
59 + 31535983 = 31536042
61 + 31535981 = 31536042
101 + 31535941 = 31536042
103 + 31535939 = 31536042
163 + 31535879 = 31536042
211 + 31535831 = 31536042
233 + 31535809 = 31536042

Showing the first eight; more decompositions exist.
