Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056142, here are decompositions:

29 + 1056113 = 1056142
53 + 1056089 = 1056142
71 + 1056071 = 1056142
89 + 1056053 = 1056142
173 + 1055969 = 1056142
359 + 1055783 = 1056142
401 + 1055741 = 1056142
599 + 1055543 = 1056142

Showing the first eight; more decompositions exist.
