Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28038, here are decompositions:

7 + 28031 = 28038
11 + 28027 = 28038
19 + 28019 = 28038
37 + 28001 = 28038
41 + 27997 = 28038
71 + 27967 = 28038
97 + 27941 = 28038
137 + 27901 = 28038

Showing the first eight; more decompositions exist.
