Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29842, here are decompositions:

5 + 29837 = 29842
23 + 29819 = 29842
53 + 29789 = 29842
83 + 29759 = 29842
89 + 29753 = 29842
101 + 29741 = 29842
173 + 29669 = 29842
179 + 29663 = 29842

Showing the first eight; more decompositions exist.
