Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29838, here are decompositions:

5 + 29833 = 29838
19 + 29819 = 29838
79 + 29759 = 29838
97 + 29741 = 29838
167 + 29671 = 29838
197 + 29641 = 29838
227 + 29611 = 29838
239 + 29599 = 29838

Showing the first eight; more decompositions exist.
