Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987616, here are decompositions:

17 + 987599 = 987616
23 + 987593 = 987616
29 + 987587 = 987616
83 + 987533 = 987616
107 + 987509 = 987616
233 + 987383 = 987616
263 + 987353 = 987616
317 + 987299 = 987616

Showing the first eight; more decompositions exist.
