Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988808, here are decompositions:

19 + 988789 = 988808
97 + 988711 = 988808
127 + 988681 = 988808
157 + 988651 = 988808
229 + 988579 = 988808
307 + 988501 = 988808
349 + 988459 = 988808
487 + 988321 = 988808

Showing the first eight; more decompositions exist.
