Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458094, here are decompositions:

11 + 31458083 = 31458094
191 + 31457903 = 31458094
233 + 31457861 = 31458094
251 + 31457843 = 31458094
263 + 31457831 = 31458094
467 + 31457627 = 31458094
491 + 31457603 = 31458094
641 + 31457453 = 31458094

Showing the first eight; more decompositions exist.
