Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987916, here are decompositions:

3 + 987913 = 987916
5 + 987911 = 987916
47 + 987869 = 987916
107 + 987809 = 987916
113 + 987803 = 987916
257 + 987659 = 987916
317 + 987599 = 987916
383 + 987533 = 987916

Showing the first eight; more decompositions exist.
