Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27578, here are decompositions:

37 + 27541 = 27578
97 + 27481 = 27578
151 + 27427 = 27578
181 + 27397 = 27578
211 + 27367 = 27578
241 + 27337 = 27578
307 + 27271 = 27578
337 + 27241 = 27578

Showing the first eight; more decompositions exist.
