Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449344, here are decompositions:

97 + 31449247 = 31449344
103 + 31449241 = 31449344
181 + 31449163 = 31449344
307 + 31449037 = 31449344
523 + 31448821 = 31449344
541 + 31448803 = 31449344
631 + 31448713 = 31449344
757 + 31448587 = 31449344

Showing the first eight; more decompositions exist.
