Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27530, here are decompositions:

3 + 27527 = 27530
43 + 27487 = 27530
73 + 27457 = 27530
103 + 27427 = 27530
163 + 27367 = 27530
193 + 27337 = 27530
271 + 27259 = 27530
277 + 27253 = 27530

Showing the first eight; more decompositions exist.
