Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987122, here are decompositions:

43 + 987079 = 987122
61 + 987061 = 987122
79 + 987043 = 987122
109 + 987013 = 987122
139 + 986983 = 987122
163 + 986959 = 987122
181 + 986941 = 987122
193 + 986929 = 987122

Showing the first eight; more decompositions exist.
