Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535184, here are decompositions:

11 + 31535173 = 31535184
13 + 31535171 = 31535184
41 + 31535143 = 31535184
53 + 31535131 = 31535184
61 + 31535123 = 31535184
71 + 31535113 = 31535184
101 + 31535083 = 31535184
103 + 31535081 = 31535184

Showing the first eight; more decompositions exist.
