Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458106, here are decompositions:

23 + 31458083 = 31458106
107 + 31457999 = 31458106
137 + 31457969 = 31458106
257 + 31457849 = 31458106
263 + 31457843 = 31458106
347 + 31457759 = 31458106
353 + 31457753 = 31458106
389 + 31457717 = 31458106

Showing the first eight; more decompositions exist.
