Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000578, here are decompositions:

31 + 1000547 = 1000578
37 + 1000541 = 1000578
41 + 1000537 = 1000578
71 + 1000507 = 1000578
149 + 1000429 = 1000578
151 + 1000427 = 1000578
181 + 1000397 = 1000578
197 + 1000381 = 1000578

Showing the first eight; more decompositions exist.
