Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493344, here are decompositions:

5 + 31493339 = 31493344
23 + 31493321 = 31493344
53 + 31493291 = 31493344
173 + 31493171 = 31493344
191 + 31493153 = 31493344
347 + 31492997 = 31493344
353 + 31492991 = 31493344
401 + 31492943 = 31493344

Showing the first eight; more decompositions exist.
