Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535922, here are decompositions:

13 + 31535909 = 31535922
43 + 31535879 = 31535922
101 + 31535821 = 31535922
113 + 31535809 = 31535922
181 + 31535741 = 31535922
241 + 31535681 = 31535922
251 + 31535671 = 31535922
283 + 31535639 = 31535922

Showing the first eight; more decompositions exist.
