Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51210, here are decompositions:

7 + 51203 = 51210
11 + 51199 = 51210
13 + 51197 = 51210
17 + 51193 = 51210
41 + 51169 = 51210
53 + 51157 = 51210
59 + 51151 = 51210
73 + 51137 = 51210

Showing the first eight; more decompositions exist.
