Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453304, here are decompositions:

37 + 31453267 = 31453304
97 + 31453207 = 31453304
163 + 31453141 = 31453304
283 + 31453021 = 31453304
331 + 31452973 = 31453304
541 + 31452763 = 31453304
577 + 31452727 = 31453304
733 + 31452571 = 31453304

Showing the first eight; more decompositions exist.
