Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15146, here are decompositions:

7 + 15139 = 15146
73 + 15073 = 15146
163 + 14983 = 15146
199 + 14947 = 15146
223 + 14923 = 15146
277 + 14869 = 15146
349 + 14797 = 15146
367 + 14779 = 15146

Showing the first eight; more decompositions exist.
