Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535352, here are decompositions:

11 + 31535341 = 31535352
31 + 31535321 = 31535352
41 + 31535311 = 31535352
89 + 31535263 = 31535352
139 + 31535213 = 31535352
179 + 31535173 = 31535352
181 + 31535171 = 31535352
229 + 31535123 = 31535352

Showing the first eight; more decompositions exist.
