Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11222, here are decompositions:

61 + 11161 = 11222
73 + 11149 = 11222
103 + 11119 = 11222
109 + 11113 = 11222
139 + 11083 = 11222
151 + 11071 = 11222
163 + 11059 = 11222
229 + 10993 = 11222

Showing the first eight; more decompositions exist.
