Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988500, here are decompositions:

11 + 988489 = 988500
17 + 988483 = 988500
41 + 988459 = 988500
47 + 988453 = 988500
61 + 988439 = 988500
83 + 988417 = 988500
157 + 988343 = 988500
179 + 988321 = 988500

Showing the first eight; more decompositions exist.
