Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546958, here are decompositions:

67 + 31546891 = 31546958
97 + 31546861 = 31546958
127 + 31546831 = 31546958
151 + 31546807 = 31546958
199 + 31546759 = 31546958
241 + 31546717 = 31546958
337 + 31546621 = 31546958
367 + 31546591 = 31546958

Showing the first eight; more decompositions exist.
