Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988512, here are decompositions:

11 + 988501 = 988512
23 + 988489 = 988512
29 + 988483 = 988512
53 + 988459 = 988512
59 + 988453 = 988512
73 + 988439 = 988512
103 + 988409 = 988512
191 + 988321 = 988512

Showing the first eight; more decompositions exist.
