Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055128, here are decompositions:

71 + 1055057 = 1055128
89 + 1055039 = 1055128
197 + 1054931 = 1055128
359 + 1054769 = 1055128
449 + 1054679 = 1055128
461 + 1054667 = 1055128
479 + 1054649 = 1055128
521 + 1054607 = 1055128

Showing the first eight; more decompositions exist.
