Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987460, here are decompositions:

3 + 987457 = 987460
107 + 987353 = 987460
167 + 987293 = 987460
233 + 987227 = 987460
251 + 987209 = 987460
269 + 987191 = 987460
317 + 987143 = 987460
359 + 987101 = 987460

Showing the first eight; more decompositions exist.
