Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51428, here are decompositions:

7 + 51421 = 51428
67 + 51361 = 51428
79 + 51349 = 51428
199 + 51229 = 51428
211 + 51217 = 51428
229 + 51199 = 51428
271 + 51157 = 51428
277 + 51151 = 51428

Showing the first eight; more decompositions exist.
