Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28946, here are decompositions:

13 + 28933 = 28946
19 + 28927 = 28946
37 + 28909 = 28946
67 + 28879 = 28946
79 + 28867 = 28946
103 + 28843 = 28946
109 + 28837 = 28946
139 + 28807 = 28946

Showing the first eight; more decompositions exist.
