Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988144, here are decompositions:

83 + 988061 = 988144
137 + 988007 = 988144
173 + 987971 = 988144
233 + 987911 = 988144
293 + 987851 = 988144
347 + 987797 = 988144
431 + 987713 = 988144
557 + 987587 = 988144

Showing the first eight; more decompositions exist.
