Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535980, here are decompositions:

41 + 31535939 = 31535980
71 + 31535909 = 31535980
101 + 31535879 = 31535980
149 + 31535831 = 31535980
227 + 31535753 = 31535980
233 + 31535747 = 31535980
239 + 31535741 = 31535980
263 + 31535717 = 31535980

Showing the first eight; more decompositions exist.
