Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15494, here are decompositions:

43 + 15451 = 15494
67 + 15427 = 15494
103 + 15391 = 15494
163 + 15331 = 15494
181 + 15313 = 15494
223 + 15271 = 15494
277 + 15217 = 15494
307 + 15187 = 15494

Showing the first eight; more decompositions exist.
