Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988434, here are decompositions:

17 + 988417 = 988434
67 + 988367 = 988434
113 + 988321 = 988434
137 + 988297 = 988434
163 + 988271 = 988434
191 + 988243 = 988434
197 + 988237 = 988434
277 + 988157 = 988434

Showing the first eight; more decompositions exist.
