Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028888, here are decompositions:

79 + 1028809 = 1028888
127 + 1028761 = 1028888
139 + 1028749 = 1028888
151 + 1028737 = 1028888
241 + 1028647 = 1028888
271 + 1028617 = 1028888
307 + 1028581 = 1028888
331 + 1028557 = 1028888

Showing the first eight; more decompositions exist.
