Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461954, here are decompositions:

5 + 31461949 = 31461954
11 + 31461943 = 31461954
31 + 31461923 = 31461954
61 + 31461893 = 31461954
67 + 31461887 = 31461954
103 + 31461851 = 31461954
113 + 31461841 = 31461954
131 + 31461823 = 31461954

Showing the first eight; more decompositions exist.
