Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11438, here are decompositions:

109 + 11329 = 11438
127 + 11311 = 11438
139 + 11299 = 11438
151 + 11287 = 11438
181 + 11257 = 11438
199 + 11239 = 11438
241 + 11197 = 11438
277 + 11161 = 11438

Showing the first eight; more decompositions exist.
