Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987450, here are decompositions:

17 + 987433 = 987450
59 + 987391 = 987450
67 + 987383 = 987450
89 + 987361 = 987450
97 + 987353 = 987450
137 + 987313 = 987450
151 + 987299 = 987450
157 + 987293 = 987450

Showing the first eight; more decompositions exist.
