Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047438, here are decompositions:

19 + 1047419 = 1047438
47 + 1047391 = 1047438
59 + 1047379 = 1047438
71 + 1047367 = 1047438
97 + 1047341 = 1047438
127 + 1047311 = 1047438
131 + 1047307 = 1047438
149 + 1047289 = 1047438

Showing the first eight; more decompositions exist.
