Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536090, here are decompositions:

29 + 31536061 = 31536090
37 + 31536053 = 31536090
41 + 31536049 = 31536090
71 + 31536019 = 31536090
73 + 31536017 = 31536090
107 + 31535983 = 31536090
109 + 31535981 = 31536090
149 + 31535941 = 31536090

Showing the first eight; more decompositions exist.
