Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583362, here are decompositions:

11 + 31583351 = 31583362
191 + 31583171 = 31583362
281 + 31583081 = 31583362
311 + 31583051 = 31583362
401 + 31582961 = 31583362
431 + 31582931 = 31583362
449 + 31582913 = 31583362
683 + 31582679 = 31583362

Showing the first eight; more decompositions exist.
