Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988940, here are decompositions:

3 + 988937 = 988940
31 + 988909 = 988940
79 + 988861 = 988940
103 + 988837 = 988940
151 + 988789 = 988940
157 + 988783 = 988940
181 + 988759 = 988940
229 + 988711 = 988940

Showing the first eight; more decompositions exist.
