Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987976, here are decompositions:

5 + 987971 = 987976
47 + 987929 = 987976
107 + 987869 = 987976
167 + 987809 = 987976
173 + 987803 = 987976
179 + 987797 = 987976
263 + 987713 = 987976
317 + 987659 = 987976

Showing the first eight; more decompositions exist.
