Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30802, here are decompositions:

29 + 30773 = 30802
89 + 30713 = 30802
113 + 30689 = 30802
131 + 30671 = 30802
263 + 30539 = 30802
293 + 30509 = 30802
311 + 30491 = 30802
353 + 30449 = 30802

Showing the first eight; more decompositions exist.
