Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026560, here are decompositions:

13 + 1026547 = 1026560
79 + 1026481 = 1026560
103 + 1026457 = 1026560
229 + 1026331 = 1026560
307 + 1026253 = 1026560
331 + 1026229 = 1026560
421 + 1026139 = 1026560
433 + 1026127 = 1026560

Showing the first eight; more decompositions exist.
