Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30954, here are decompositions:

5 + 30949 = 30954
13 + 30941 = 30954
17 + 30937 = 30954
23 + 30931 = 30954
43 + 30911 = 30954
61 + 30893 = 30954
73 + 30881 = 30954
83 + 30871 = 30954

Showing the first eight; more decompositions exist.
