Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987598, here are decompositions:

5 + 987593 = 987598
11 + 987587 = 987598
89 + 987509 = 987598
107 + 987491 = 987598
347 + 987251 = 987598
389 + 987209 = 987598
509 + 987089 = 987598
569 + 987029 = 987598

Showing the first eight; more decompositions exist.
