Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29138, here are decompositions:

7 + 29131 = 29138
37 + 29101 = 29138
61 + 29077 = 29138
79 + 29059 = 29138
211 + 28927 = 29138
229 + 28909 = 29138
271 + 28867 = 29138
331 + 28807 = 29138

Showing the first eight; more decompositions exist.
