Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017578, here are decompositions:

19 + 1017559 = 1017578
97 + 1017481 = 1017578
139 + 1017439 = 1017578
271 + 1017307 = 1017578
277 + 1017301 = 1017578
379 + 1017199 = 1017578
421 + 1017157 = 1017578
439 + 1017139 = 1017578

Showing the first eight; more decompositions exist.
