Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988670, here are decompositions:

19 + 988651 = 988670
79 + 988591 = 988670
181 + 988489 = 988670
211 + 988459 = 988670
313 + 988357 = 988670
349 + 988321 = 988670
373 + 988297 = 988670
433 + 988237 = 988670

Showing the first eight; more decompositions exist.
