Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453058, here are decompositions:

19 + 31453039 = 31453058
37 + 31453021 = 31453058
157 + 31452901 = 31453058
199 + 31452859 = 31453058
229 + 31452829 = 31453058
331 + 31452727 = 31453058
337 + 31452721 = 31453058
409 + 31452649 = 31453058

Showing the first eight; more decompositions exist.
