Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987556, here are decompositions:

23 + 987533 = 987556
47 + 987509 = 987556
83 + 987473 = 987556
173 + 987383 = 987556
257 + 987299 = 987556
263 + 987293 = 987556
347 + 987209 = 987556
467 + 987089 = 987556

Showing the first eight; more decompositions exist.
