Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988580, here are decompositions:

3 + 988577 = 988580
31 + 988549 = 988580
79 + 988501 = 988580
97 + 988483 = 988580
127 + 988453 = 988580
163 + 988417 = 988580
223 + 988357 = 988580
283 + 988297 = 988580

Showing the first eight; more decompositions exist.
