Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988156, here are decompositions:

47 + 988109 = 988156
89 + 988067 = 988156
149 + 988007 = 988156
173 + 987983 = 988156
227 + 987929 = 988156
347 + 987809 = 988156
353 + 987803 = 988156
359 + 987797 = 988156

Showing the first eight; more decompositions exist.
