Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987744, here are decompositions:

5 + 987739 = 987744
31 + 987713 = 987744
47 + 987697 = 987744
113 + 987631 = 987744
137 + 987607 = 987744
151 + 987593 = 987744
157 + 987587 = 987744
211 + 987533 = 987744

Showing the first eight; more decompositions exist.
