Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535982, here are decompositions:

41 + 31535941 = 31535982
43 + 31535939 = 31535982
73 + 31535909 = 31535982
103 + 31535879 = 31535982
151 + 31535831 = 31535982
173 + 31535809 = 31535982
229 + 31535753 = 31535982
241 + 31535741 = 31535982

Showing the first eight; more decompositions exist.
