Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961172, here are decompositions:

13 + 961159 = 961172
31 + 961141 = 961172
73 + 961099 = 961172
103 + 961069 = 961172
109 + 961063 = 961172
139 + 961033 = 961172
151 + 961021 = 961172
181 + 960991 = 961172

Showing the first eight; more decompositions exist.
