Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989686, here are decompositions:

23 + 989663 = 989686
107 + 989579 = 989686
179 + 989507 = 989686
263 + 989423 = 989686
359 + 989327 = 989686
563 + 989123 = 989686
587 + 989099 = 989686
809 + 988877 = 989686

Showing the first eight; more decompositions exist.
