Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51398, here are decompositions:

37 + 51361 = 51398
157 + 51241 = 51398
181 + 51217 = 51398
199 + 51199 = 51398
229 + 51169 = 51398
241 + 51157 = 51398
337 + 51061 = 51398
367 + 51031 = 51398

Showing the first eight; more decompositions exist.
