Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28220, here are decompositions:

19 + 28201 = 28220
37 + 28183 = 28220
97 + 28123 = 28220
109 + 28111 = 28220
139 + 28081 = 28220
151 + 28069 = 28220
163 + 28057 = 28220
193 + 28027 = 28220

Showing the first eight; more decompositions exist.
