Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11220, here are decompositions:

7 + 11213 = 11220
23 + 11197 = 11220
43 + 11177 = 11220
47 + 11173 = 11220
59 + 11161 = 11220
61 + 11159 = 11220
71 + 11149 = 11220
89 + 11131 = 11220

Showing the first eight; more decompositions exist.
