Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126012, here are decompositions:

11 + 126001 = 126012
53 + 125959 = 126012
71 + 125941 = 126012
79 + 125933 = 126012
83 + 125929 = 126012
113 + 125899 = 126012
149 + 125863 = 126012
191 + 125821 = 126012

Showing the first eight; more decompositions exist.
