Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987558, here are decompositions:

17 + 987541 = 987558
67 + 987491 = 987558
101 + 987457 = 987558
167 + 987391 = 987558
197 + 987361 = 987558
307 + 987251 = 987558
331 + 987227 = 987558
347 + 987211 = 987558

Showing the first eight; more decompositions exist.
