Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988878, here are decompositions:

17 + 988861 = 988878
19 + 988859 = 988878
29 + 988849 = 988878
41 + 988837 = 988878
89 + 988789 = 988878
151 + 988727 = 988878
167 + 988711 = 988878
197 + 988681 = 988878

Showing the first eight; more decompositions exist.
