Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535892, here are decompositions:

13 + 31535879 = 31535892
61 + 31535831 = 31535892
71 + 31535821 = 31535892
83 + 31535809 = 31535892
139 + 31535753 = 31535892
151 + 31535741 = 31535892
211 + 31535681 = 31535892
389 + 31535503 = 31535892

Showing the first eight; more decompositions exist.
