Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535310, here are decompositions:

47 + 31535263 = 31535310
83 + 31535227 = 31535310
97 + 31535213 = 31535310
127 + 31535183 = 31535310
137 + 31535173 = 31535310
139 + 31535171 = 31535310
167 + 31535143 = 31535310
179 + 31535131 = 31535310

Showing the first eight; more decompositions exist.
