Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055638, here are decompositions:

29 + 1055609 = 1055638
41 + 1055597 = 1055638
47 + 1055591 = 1055638
71 + 1055567 = 1055638
107 + 1055531 = 1055638
137 + 1055501 = 1055638
149 + 1055489 = 1055638
167 + 1055471 = 1055638

Showing the first eight; more decompositions exist.
