Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583464, here are decompositions:

41 + 31583423 = 31583464
113 + 31583351 = 31583464
293 + 31583171 = 31583464
317 + 31583147 = 31583464
383 + 31583081 = 31583464
431 + 31583033 = 31583464
503 + 31582961 = 31583464
557 + 31582907 = 31583464

Showing the first eight; more decompositions exist.
