Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27430, here are decompositions:

3 + 27427 = 27430
23 + 27407 = 27430
101 + 27329 = 27430
131 + 27299 = 27430
149 + 27281 = 27430
191 + 27239 = 27430
233 + 27197 = 27430
239 + 27191 = 27430

Showing the first eight; more decompositions exist.
