Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535808, here are decompositions:

11 + 31535797 = 31535808
61 + 31535747 = 31535808
67 + 31535741 = 31535808
127 + 31535681 = 31535808
137 + 31535671 = 31535808
151 + 31535657 = 31535808
257 + 31535551 = 31535808
379 + 31535429 = 31535808

Showing the first eight; more decompositions exist.
