Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987484, here are decompositions:

11 + 987473 = 987484
101 + 987383 = 987484
131 + 987353 = 987484
191 + 987293 = 987484
233 + 987251 = 987484
257 + 987227 = 987484
293 + 987191 = 987484
383 + 987101 = 987484

Showing the first eight; more decompositions exist.
