Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987490, here are decompositions:

17 + 987473 = 987490
107 + 987383 = 987490
137 + 987353 = 987490
191 + 987299 = 987490
197 + 987293 = 987490
239 + 987251 = 987490
263 + 987227 = 987490
281 + 987209 = 987490

Showing the first eight; more decompositions exist.
