Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987588, here are decompositions:

29 + 987559 = 987588
47 + 987541 = 987588
79 + 987509 = 987588
97 + 987491 = 987588
131 + 987457 = 987588
197 + 987391 = 987588
227 + 987361 = 987588
337 + 987251 = 987588

Showing the first eight; more decompositions exist.
