Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458052, here are decompositions:

53 + 31457999 = 31458052
83 + 31457969 = 31458052
149 + 31457903 = 31458052
191 + 31457861 = 31458052
233 + 31457819 = 31458052
281 + 31457771 = 31458052
293 + 31457759 = 31458052
449 + 31457603 = 31458052

Showing the first eight; more decompositions exist.
