Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026644, here are decompositions:

61 + 1026583 = 1026644
67 + 1026577 = 1026644
97 + 1026547 = 1026644
163 + 1026481 = 1026644
313 + 1026331 = 1026644
331 + 1026313 = 1026644
571 + 1026073 = 1026644
601 + 1026043 = 1026644

Showing the first eight; more decompositions exist.
