Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51238, here are decompositions:

41 + 51197 = 51238
101 + 51137 = 51238
107 + 51131 = 51238
167 + 51071 = 51238
179 + 51059 = 51238
191 + 51047 = 51238
269 + 50969 = 51238
281 + 50957 = 51238

Showing the first eight; more decompositions exist.
