Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453124, here are decompositions:

103 + 31453021 = 31453124
151 + 31452973 = 31453124
181 + 31452943 = 31453124
223 + 31452901 = 31453124
331 + 31452793 = 31453124
397 + 31452727 = 31453124
457 + 31452667 = 31453124
541 + 31452583 = 31453124

Showing the first eight; more decompositions exist.
