Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453032, here are decompositions:

11 + 31453021 = 31453032
59 + 31452973 = 31453032
89 + 31452943 = 31453032
131 + 31452901 = 31453032
173 + 31452859 = 31453032
181 + 31452851 = 31453032
229 + 31452803 = 31453032
239 + 31452793 = 31453032

Showing the first eight; more decompositions exist.
