Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583344, here are decompositions:

173 + 31583171 = 31583344
197 + 31583147 = 31583344
257 + 31583087 = 31583344
263 + 31583081 = 31583344
293 + 31583051 = 31583344
311 + 31583033 = 31583344
383 + 31582961 = 31583344
431 + 31582913 = 31583344

Showing the first eight; more decompositions exist.
