Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11258, here are decompositions:

7 + 11251 = 11258
19 + 11239 = 11258
61 + 11197 = 11258
97 + 11161 = 11258
109 + 11149 = 11258
127 + 11131 = 11258
139 + 11119 = 11258
199 + 11059 = 11258

Showing the first eight; more decompositions exist.
