Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988172, here are decompositions:

43 + 988129 = 988172
61 + 988111 = 988172
79 + 988093 = 988172
103 + 988069 = 988172
139 + 988033 = 988172
151 + 988021 = 988172
181 + 987991 = 988172
193 + 987979 = 988172

Showing the first eight; more decompositions exist.
