Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988884, here are decompositions:

7 + 988877 = 988884
23 + 988861 = 988884
47 + 988837 = 988884
101 + 988783 = 988884
151 + 988733 = 988884
157 + 988727 = 988884
173 + 988711 = 988884
191 + 988693 = 988884

Showing the first eight; more decompositions exist.
