Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164278, here are decompositions:

11 + 164267 = 164278
29 + 164249 = 164278
47 + 164231 = 164278
131 + 164147 = 164278
227 + 164051 = 164278
239 + 164039 = 164278
281 + 163997 = 164278
419 + 163859 = 164278

Showing the first eight; more decompositions exist.
