Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987182, here are decompositions:

103 + 987079 = 987182
139 + 987043 = 987182
193 + 986989 = 987182
199 + 986983 = 987182
223 + 986959 = 987182
241 + 986941 = 987182
331 + 986851 = 987182
433 + 986749 = 987182

Showing the first eight; more decompositions exist.
