Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51208, here are decompositions:

5 + 51203 = 51208
11 + 51197 = 51208
71 + 51137 = 51208
137 + 51071 = 51208
149 + 51059 = 51208
239 + 50969 = 51208
251 + 50957 = 51208
257 + 50951 = 51208

Showing the first eight; more decompositions exist.
