Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533344, here are decompositions:

211 + 31533133 = 31533344
331 + 31533013 = 31533344
373 + 31532971 = 31533344
421 + 31532923 = 31533344
463 + 31532881 = 31533344
607 + 31532737 = 31533344
691 + 31532653 = 31533344
751 + 31532593 = 31533344

Showing the first eight; more decompositions exist.
