Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125988, here are decompositions:

29 + 125959 = 125988
47 + 125941 = 125988
59 + 125929 = 125988
61 + 125927 = 125988
67 + 125921 = 125988
89 + 125899 = 125988
101 + 125887 = 125988
167 + 125821 = 125988

Showing the first eight; more decompositions exist.
