Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465958, here are decompositions:

67 + 31465891 = 31465958
79 + 31465879 = 31465958
109 + 31465849 = 31465958
127 + 31465831 = 31465958
157 + 31465801 = 31465958
211 + 31465747 = 31465958
379 + 31465579 = 31465958
397 + 31465561 = 31465958

Showing the first eight; more decompositions exist.
