Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455344, here are decompositions:

31 + 31455313 = 31455344
43 + 31455301 = 31455344
73 + 31455271 = 31455344
223 + 31455121 = 31455344
241 + 31455103 = 31455344
313 + 31455031 = 31455344
373 + 31454971 = 31455344
421 + 31454923 = 31455344

Showing the first eight; more decompositions exist.
