Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583352, here are decompositions:

29 + 31583323 = 31583352
71 + 31583281 = 31583352
83 + 31583269 = 31583352
181 + 31583171 = 31583352
193 + 31583159 = 31583352
271 + 31583081 = 31583352
401 + 31582951 = 31583352
421 + 31582931 = 31583352

Showing the first eight; more decompositions exist.
