Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27270, here are decompositions:

11 + 27259 = 27270
17 + 27253 = 27270
29 + 27241 = 27270
31 + 27239 = 27270
59 + 27211 = 27270
73 + 27197 = 27270
79 + 27191 = 27270
127 + 27143 = 27270

Showing the first eight; more decompositions exist.
