Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51380, here are decompositions:

19 + 51361 = 51380
31 + 51349 = 51380
37 + 51343 = 51380
73 + 51307 = 51380
97 + 51283 = 51380
139 + 51241 = 51380
151 + 51229 = 51380
163 + 51217 = 51380

Showing the first eight; more decompositions exist.
