Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988470, here are decompositions:

11 + 988459 = 988470
17 + 988453 = 988470
31 + 988439 = 988470
53 + 988417 = 988470
61 + 988409 = 988470
103 + 988367 = 988470
113 + 988357 = 988470
127 + 988343 = 988470

Showing the first eight; more decompositions exist.
