Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51358, here are decompositions:

11 + 51347 = 51358
17 + 51341 = 51358
29 + 51329 = 51358
71 + 51287 = 51358
101 + 51257 = 51358
227 + 51131 = 51358
311 + 51047 = 51358
389 + 50969 = 51358

Showing the first eight; more decompositions exist.
