Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988386, here are decompositions:

19 + 988367 = 988386
29 + 988357 = 988386
43 + 988343 = 988386
67 + 988319 = 988386
73 + 988313 = 988386
89 + 988297 = 988386
107 + 988279 = 988386
149 + 988237 = 988386

Showing the first eight; more decompositions exist.
