Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987544, here are decompositions:

3 + 987541 = 987544
11 + 987533 = 987544
53 + 987491 = 987544
71 + 987473 = 987544
191 + 987353 = 987544
251 + 987293 = 987544
293 + 987251 = 987544
317 + 987227 = 987544

Showing the first eight; more decompositions exist.
