Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458232, here are decompositions:

41 + 31458191 = 31458232
59 + 31458173 = 31458232
101 + 31458131 = 31458232
149 + 31458083 = 31458232
233 + 31457999 = 31458232
263 + 31457969 = 31458232
383 + 31457849 = 31458232
389 + 31457843 = 31458232

Showing the first eight; more decompositions exist.
