Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453424, here are decompositions:

3 + 31453421 = 31453424
31 + 31453393 = 31453424
103 + 31453321 = 31453424
157 + 31453267 = 31453424
283 + 31453141 = 31453424
523 + 31452901 = 31453424
631 + 31452793 = 31453424
661 + 31452763 = 31453424

Showing the first eight; more decompositions exist.
