Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29180, here are decompositions:

7 + 29173 = 29180
13 + 29167 = 29180
43 + 29137 = 29180
79 + 29101 = 29180
103 + 29077 = 29180
157 + 29023 = 29180
163 + 29017 = 29180
271 + 28909 = 29180

Showing the first eight; more decompositions exist.
