Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988198, here are decompositions:

41 + 988157 = 988198
89 + 988109 = 988198
131 + 988067 = 988198
137 + 988061 = 988198
191 + 988007 = 988198
227 + 987971 = 988198
257 + 987941 = 988198
269 + 987929 = 988198

Showing the first eight; more decompositions exist.
