Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535160, here are decompositions:

17 + 31535143 = 31535160
29 + 31535131 = 31535160
37 + 31535123 = 31535160
47 + 31535113 = 31535160
53 + 31535107 = 31535160
79 + 31535081 = 31535160
101 + 31535059 = 31535160
103 + 31535057 = 31535160

Showing the first eight; more decompositions exist.
