Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988286, here are decompositions:

7 + 988279 = 988286
43 + 988243 = 988286
67 + 988219 = 988286
73 + 988213 = 988286
139 + 988147 = 988286
157 + 988129 = 988286
193 + 988093 = 988286
307 + 987979 = 988286

Showing the first eight; more decompositions exist.
