Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987946, here are decompositions:

5 + 987941 = 987946
17 + 987929 = 987946
137 + 987809 = 987946
149 + 987797 = 987946
233 + 987713 = 987946
347 + 987599 = 987946
353 + 987593 = 987946
359 + 987587 = 987946

Showing the first eight; more decompositions exist.
