Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29428, here are decompositions:

5 + 29423 = 29428
17 + 29411 = 29428
29 + 29399 = 29428
41 + 29387 = 29428
89 + 29339 = 29428
101 + 29327 = 29428
131 + 29297 = 29428
197 + 29231 = 29428

Showing the first eight; more decompositions exist.
