Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29818, here are decompositions:

29 + 29789 = 29818
59 + 29759 = 29818
101 + 29717 = 29818
149 + 29669 = 29818
251 + 29567 = 29818
281 + 29537 = 29818
317 + 29501 = 29818
389 + 29429 = 29818

Showing the first eight; more decompositions exist.
