Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453152, here are decompositions:

11 + 31453141 = 31453152
19 + 31453133 = 31453152
113 + 31453039 = 31453152
131 + 31453021 = 31453152
179 + 31452973 = 31453152
251 + 31452901 = 31453152
293 + 31452859 = 31453152
349 + 31452803 = 31453152

Showing the first eight; more decompositions exist.
