Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988664, here are decompositions:

3 + 988661 = 988664
13 + 988651 = 988664
73 + 988591 = 988664
163 + 988501 = 988664
181 + 988483 = 988664
211 + 988453 = 988664
307 + 988357 = 988664
367 + 988297 = 988664

Showing the first eight; more decompositions exist.
