Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458344, here are decompositions:

13 + 31458331 = 31458344
67 + 31458277 = 31458344
157 + 31458187 = 31458344
283 + 31458061 = 31458344
331 + 31458013 = 31458344
433 + 31457911 = 31458344
487 + 31457857 = 31458344
523 + 31457821 = 31458344

Showing the first eight; more decompositions exist.
