Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988634, here are decompositions:

43 + 988591 = 988634
151 + 988483 = 988634
181 + 988453 = 988634
277 + 988357 = 988634
313 + 988321 = 988634
337 + 988297 = 988634
397 + 988237 = 988634
421 + 988213 = 988634

Showing the first eight; more decompositions exist.
