Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12542, here are decompositions:

3 + 12539 = 12542
31 + 12511 = 12542
109 + 12433 = 12542
151 + 12391 = 12542
163 + 12379 = 12542
199 + 12343 = 12542
241 + 12301 = 12542
331 + 12211 = 12542

Showing the first eight; more decompositions exist.
