Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987798, here are decompositions:

5 + 987793 = 987798
59 + 987739 = 987798
101 + 987697 = 987798
139 + 987659 = 987798
167 + 987631 = 987798
191 + 987607 = 987798
199 + 987599 = 987798
211 + 987587 = 987798

Showing the first eight; more decompositions exist.
