Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11498, here are decompositions:

7 + 11491 = 11498
31 + 11467 = 11498
61 + 11437 = 11498
181 + 11317 = 11498
199 + 11299 = 11498
211 + 11287 = 11498
241 + 11257 = 11498
337 + 11161 = 11498

Showing the first eight; more decompositions exist.
