Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28106, here are decompositions:

7 + 28099 = 28106
19 + 28087 = 28106
37 + 28069 = 28106
79 + 28027 = 28106
109 + 27997 = 28106
139 + 27967 = 28106
163 + 27943 = 28106
223 + 27883 = 28106

Showing the first eight; more decompositions exist.
