Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988736, here are decompositions:

3 + 988733 = 988736
43 + 988693 = 988736
157 + 988579 = 988736
277 + 988459 = 988736
283 + 988453 = 988736
379 + 988357 = 988736
439 + 988297 = 988736
457 + 988279 = 988736

Showing the first eight; more decompositions exist.
