Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51360, here are decompositions:

11 + 51349 = 51360
13 + 51347 = 51360
17 + 51343 = 51360
19 + 51341 = 51360
31 + 51329 = 51360
53 + 51307 = 51360
73 + 51287 = 51360
97 + 51263 = 51360

Showing the first eight; more decompositions exist.
