Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018424, here are decompositions:

3 + 1018421 = 1018424
13 + 1018411 = 1018424
67 + 1018357 = 1018424
223 + 1018201 = 1018424
367 + 1018057 = 1018424
577 + 1017847 = 1018424
607 + 1017817 = 1018424
643 + 1017781 = 1018424

Showing the first eight; more decompositions exist.
