Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988700, here are decompositions:

7 + 988693 = 988700
19 + 988681 = 988700
109 + 988591 = 988700
151 + 988549 = 988700
199 + 988501 = 988700
211 + 988489 = 988700
241 + 988459 = 988700
283 + 988417 = 988700

Showing the first eight; more decompositions exist.
