Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583256, here are decompositions:

97 + 31583159 = 31583256
109 + 31583147 = 31583256
223 + 31583033 = 31583256
233 + 31583023 = 31583256
307 + 31582949 = 31583256
349 + 31582907 = 31583256
359 + 31582897 = 31583256
409 + 31582847 = 31583256

Showing the first eight; more decompositions exist.
