Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28226, here are decompositions:

7 + 28219 = 28226
43 + 28183 = 28226
103 + 28123 = 28226
127 + 28099 = 28226
139 + 28087 = 28226
157 + 28069 = 28226
199 + 28027 = 28226
229 + 27997 = 28226

Showing the first eight; more decompositions exist.
