Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458234, here are decompositions:

37 + 31458197 = 31458234
43 + 31458191 = 31458234
47 + 31458187 = 31458234
61 + 31458173 = 31458234
103 + 31458131 = 31458234
151 + 31458083 = 31458234
173 + 31458061 = 31458234
331 + 31457903 = 31458234

Showing the first eight; more decompositions exist.
