Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472958, here are decompositions:

29 + 31472929 = 31472958
31 + 31472927 = 31472958
67 + 31472891 = 31472958
71 + 31472887 = 31472958
79 + 31472879 = 31472958
107 + 31472851 = 31472958
109 + 31472849 = 31472958
131 + 31472827 = 31472958

Showing the first eight; more decompositions exist.
