Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987910, here are decompositions:

41 + 987869 = 987910
59 + 987851 = 987910
89 + 987821 = 987910
101 + 987809 = 987910
107 + 987803 = 987910
113 + 987797 = 987910
197 + 987713 = 987910
251 + 987659 = 987910

Showing the first eight; more decompositions exist.
