Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017420, here are decompositions:

29 + 1017391 = 1017420
37 + 1017383 = 1017420
43 + 1017377 = 1017420
59 + 1017361 = 1017420
67 + 1017353 = 1017420
73 + 1017347 = 1017420
97 + 1017323 = 1017420
101 + 1017319 = 1017420

Showing the first eight; more decompositions exist.
