Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583286, here are decompositions:

5 + 31583281 = 31583286
17 + 31583269 = 31583286
29 + 31583257 = 31583286
127 + 31583159 = 31583286
139 + 31583147 = 31583286
149 + 31583137 = 31583286
199 + 31583087 = 31583286
239 + 31583047 = 31583286

Showing the first eight; more decompositions exist.
