Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042558, here are decompositions:

29 + 1042529 = 1042558
71 + 1042487 = 1042558
89 + 1042469 = 1042558
107 + 1042451 = 1042558
131 + 1042427 = 1042558
227 + 1042331 = 1042558
317 + 1042241 = 1042558
347 + 1042211 = 1042558

Showing the first eight; more decompositions exist.
