Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453122, here are decompositions:

83 + 31453039 = 31453122
101 + 31453021 = 31453122
149 + 31452973 = 31453122
179 + 31452943 = 31453122
263 + 31452859 = 31453122
271 + 31452851 = 31453122
293 + 31452829 = 31453122
353 + 31452769 = 31453122

Showing the first eight; more decompositions exist.
