Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583292, here are decompositions:

11 + 31583281 = 31583292
23 + 31583269 = 31583292
211 + 31583081 = 31583292
241 + 31583051 = 31583292
269 + 31583023 = 31583292
311 + 31582981 = 31583292
331 + 31582961 = 31583292
379 + 31582913 = 31583292

Showing the first eight; more decompositions exist.
