Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30876, here are decompositions:

5 + 30871 = 30876
7 + 30869 = 30876
17 + 30859 = 30876
23 + 30853 = 30876
37 + 30839 = 30876
47 + 30829 = 30876
59 + 30817 = 30876
67 + 30809 = 30876

Showing the first eight; more decompositions exist.
