Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583310, here are decompositions:

29 + 31583281 = 31583310
41 + 31583269 = 31583310
53 + 31583257 = 31583310
139 + 31583171 = 31583310
151 + 31583159 = 31583310
163 + 31583147 = 31583310
173 + 31583137 = 31583310
179 + 31583131 = 31583310

Showing the first eight; more decompositions exist.
