Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535976, here are decompositions:

29 + 31535947 = 31535976
37 + 31535939 = 31535976
67 + 31535909 = 31535976
97 + 31535879 = 31535976
149 + 31535827 = 31535976
167 + 31535809 = 31535976
179 + 31535797 = 31535976
223 + 31535753 = 31535976

Showing the first eight; more decompositions exist.
