Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51418, here are decompositions:

5 + 51413 = 51418
11 + 51407 = 51418
71 + 51347 = 51418
89 + 51329 = 51418
131 + 51287 = 51418
179 + 51239 = 51418
281 + 51137 = 51418
347 + 51071 = 51418

Showing the first eight; more decompositions exist.
