Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988522, here are decompositions:

11 + 988511 = 988522
83 + 988439 = 988522
113 + 988409 = 988522
179 + 988343 = 988522
251 + 988271 = 988522
461 + 988061 = 988522
593 + 987929 = 988522
653 + 987869 = 988522

Showing the first eight; more decompositions exist.
