Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583262, here are decompositions:

5 + 31583257 = 31583262
103 + 31583159 = 31583262
131 + 31583131 = 31583262
181 + 31583081 = 31583262
211 + 31583051 = 31583262
229 + 31583033 = 31583262
239 + 31583023 = 31583262
281 + 31582981 = 31583262

Showing the first eight; more decompositions exist.
