Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29156, here are decompositions:

3 + 29153 = 29156
19 + 29137 = 29156
79 + 29077 = 29156
97 + 29059 = 29156
139 + 29017 = 29156
223 + 28933 = 29156
229 + 28927 = 29156
277 + 28879 = 29156

Showing the first eight; more decompositions exist.
