Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987894, here are decompositions:

43 + 987851 = 987894
73 + 987821 = 987894
97 + 987797 = 987894
101 + 987793 = 987894
181 + 987713 = 987894
197 + 987697 = 987894
263 + 987631 = 987894
307 + 987587 = 987894

Showing the first eight; more decompositions exist.
