Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458934, here are decompositions:

11 + 31458923 = 31458934
71 + 31458863 = 31458934
113 + 31458821 = 31458934
137 + 31458797 = 31458934
173 + 31458761 = 31458934
233 + 31458701 = 31458934
347 + 31458587 = 31458934
503 + 31458431 = 31458934

Showing the first eight; more decompositions exist.
