Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27242, here are decompositions:

3 + 27239 = 27242
31 + 27211 = 27242
139 + 27103 = 27242
151 + 27091 = 27242
181 + 27061 = 27242
199 + 27043 = 27242
211 + 27031 = 27242
283 + 26959 = 27242

Showing the first eight; more decompositions exist.
