Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22280, here are decompositions:

3 + 22277 = 22280
7 + 22273 = 22280
109 + 22171 = 22280
127 + 22153 = 22280
151 + 22129 = 22280
157 + 22123 = 22280
229 + 22051 = 22280
241 + 22039 = 22280

Showing the first eight; more decompositions exist.
