Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535958, here are decompositions:

11 + 31535947 = 31535958
17 + 31535941 = 31535958
19 + 31535939 = 31535958
79 + 31535879 = 31535958
127 + 31535831 = 31535958
131 + 31535827 = 31535958
137 + 31535821 = 31535958
149 + 31535809 = 31535958

Showing the first eight; more decompositions exist.
