Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988520, here are decompositions:

19 + 988501 = 988520
31 + 988489 = 988520
37 + 988483 = 988520
61 + 988459 = 988520
67 + 988453 = 988520
103 + 988417 = 988520
163 + 988357 = 988520
199 + 988321 = 988520

Showing the first eight; more decompositions exist.
