Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961142, here are decompositions:

3 + 961139 = 961142
19 + 961123 = 961142
43 + 961099 = 961142
73 + 961069 = 961142
79 + 961063 = 961142
109 + 961033 = 961142
139 + 961003 = 961142
151 + 960991 = 961142

Showing the first eight; more decompositions exist.
