Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30982, here are decompositions:

5 + 30977 = 30982
11 + 30971 = 30982
41 + 30941 = 30982
71 + 30911 = 30982
89 + 30893 = 30982
101 + 30881 = 30982
113 + 30869 = 30982
131 + 30851 = 30982

Showing the first eight; more decompositions exist.
