Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987320, here are decompositions:

7 + 987313 = 987320
109 + 987211 = 987320
127 + 987193 = 987320
193 + 987127 = 987320
223 + 987097 = 987320
241 + 987079 = 987320
277 + 987043 = 987320
307 + 987013 = 987320

Showing the first eight; more decompositions exist.
