Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458348, here are decompositions:

17 + 31458331 = 31458348
37 + 31458311 = 31458348
71 + 31458277 = 31458348
109 + 31458239 = 31458348
151 + 31458197 = 31458348
157 + 31458191 = 31458348
179 + 31458169 = 31458348
349 + 31457999 = 31458348

Showing the first eight; more decompositions exist.
