Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29806, here are decompositions:

3 + 29803 = 29806
17 + 29789 = 29806
47 + 29759 = 29806
53 + 29753 = 29806
83 + 29723 = 29806
89 + 29717 = 29806
137 + 29669 = 29806
173 + 29633 = 29806

Showing the first eight; more decompositions exist.
