Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009578, here are decompositions:

5 + 1009573 = 1009578
19 + 1009559 = 1009578
41 + 1009537 = 1009578
47 + 1009531 = 1009578
71 + 1009507 = 1009578
79 + 1009499 = 1009578
139 + 1009439 = 1009578
179 + 1009399 = 1009578

Showing the first eight; more decompositions exist.
