Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18494, here are decompositions:

13 + 18481 = 18494
37 + 18457 = 18494
43 + 18451 = 18494
61 + 18433 = 18494
67 + 18427 = 18494
97 + 18397 = 18494
127 + 18367 = 18494
181 + 18313 = 18494

Showing the first eight; more decompositions exist.
