Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453052, here are decompositions:

13 + 31453039 = 31453052
31 + 31453021 = 31453052
79 + 31452973 = 31453052
109 + 31452943 = 31453052
151 + 31452901 = 31453052
193 + 31452859 = 31453052
223 + 31452829 = 31453052
283 + 31452769 = 31453052

Showing the first eight; more decompositions exist.
