Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988942, here are decompositions:

5 + 988937 = 988942
41 + 988901 = 988942
83 + 988859 = 988942
113 + 988829 = 988942
179 + 988763 = 988942
281 + 988661 = 988942
293 + 988649 = 988942
359 + 988583 = 988942

Showing the first eight; more decompositions exist.
