Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987934, here are decompositions:

5 + 987929 = 987934
23 + 987911 = 987934
83 + 987851 = 987934
113 + 987821 = 987934
131 + 987803 = 987934
137 + 987797 = 987934
347 + 987587 = 987934
401 + 987533 = 987934

Showing the first eight; more decompositions exist.
