Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055430, here are decompositions:

7 + 1055423 = 1055430
17 + 1055413 = 1055430
23 + 1055407 = 1055430
31 + 1055399 = 1055430
43 + 1055387 = 1055430
59 + 1055371 = 1055430
67 + 1055363 = 1055430
71 + 1055359 = 1055430

Showing the first eight; more decompositions exist.
