Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535898, here are decompositions:

19 + 31535879 = 31535898
67 + 31535831 = 31535898
71 + 31535827 = 31535898
89 + 31535809 = 31535898
101 + 31535797 = 31535898
151 + 31535747 = 31535898
157 + 31535741 = 31535898
181 + 31535717 = 31535898

Showing the first eight; more decompositions exist.
