Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987498, here are decompositions:

7 + 987491 = 987498
41 + 987457 = 987498
107 + 987391 = 987498
137 + 987361 = 987498
199 + 987299 = 987498
271 + 987227 = 987498
307 + 987191 = 987498
397 + 987101 = 987498

Showing the first eight; more decompositions exist.
