Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969142, here are decompositions:

3 + 969139 = 969142
11 + 969131 = 969142
29 + 969113 = 969142
59 + 969083 = 969142
71 + 969071 = 969142
101 + 969041 = 969142
131 + 969011 = 969142
179 + 968963 = 969142

Showing the first eight; more decompositions exist.
