Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987098, here are decompositions:

19 + 987079 = 987098
31 + 987067 = 987098
37 + 987061 = 987098
109 + 986989 = 987098
139 + 986959 = 987098
157 + 986941 = 987098
241 + 986857 = 987098
331 + 986767 = 987098

Showing the first eight; more decompositions exist.
