Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164280, here are decompositions:

13 + 164267 = 164280
29 + 164251 = 164280
31 + 164249 = 164280
41 + 164239 = 164280
47 + 164233 = 164280
71 + 164209 = 164280
79 + 164201 = 164280
89 + 164191 = 164280

Showing the first eight; more decompositions exist.
