Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29866, here are decompositions:

3 + 29863 = 29866
29 + 29837 = 29866
47 + 29819 = 29866
107 + 29759 = 29866
113 + 29753 = 29866
149 + 29717 = 29866
197 + 29669 = 29866
233 + 29633 = 29866

Showing the first eight; more decompositions exist.
