Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453010, here are decompositions:

37 + 31452973 = 31453010
67 + 31452943 = 31453010
109 + 31452901 = 31453010
151 + 31452859 = 31453010
181 + 31452829 = 31453010
241 + 31452769 = 31453010
271 + 31452739 = 31453010
283 + 31452727 = 31453010

Showing the first eight; more decompositions exist.
