Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535328, here are decompositions:

7 + 31535321 = 31535328
17 + 31535311 = 31535328
101 + 31535227 = 31535328
109 + 31535219 = 31535328
157 + 31535171 = 31535328
197 + 31535131 = 31535328
269 + 31535059 = 31535328
271 + 31535057 = 31535328

Showing the first eight; more decompositions exist.
