Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51802, here are decompositions:

5 + 51797 = 51802
53 + 51749 = 51802
83 + 51719 = 51802
89 + 51713 = 51802
239 + 51563 = 51802
251 + 51551 = 51802
263 + 51539 = 51802
281 + 51521 = 51802

Showing the first eight; more decompositions exist.
