Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30894, here are decompositions:

13 + 30881 = 30894
23 + 30871 = 30894
41 + 30853 = 30894
43 + 30851 = 30894
53 + 30841 = 30894
113 + 30781 = 30894
131 + 30763 = 30894
137 + 30757 = 30894

Showing the first eight; more decompositions exist.
