Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29878, here are decompositions:

5 + 29873 = 29878
11 + 29867 = 29878
41 + 29837 = 29878
59 + 29819 = 29878
89 + 29789 = 29878
137 + 29741 = 29878
311 + 29567 = 29878
347 + 29531 = 29878

Showing the first eight; more decompositions exist.
