Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961228, here are decompositions:

41 + 961187 = 961228
71 + 961157 = 961228
89 + 961139 = 961228
131 + 961097 = 961228
137 + 961091 = 961228
239 + 960989 = 961228
251 + 960977 = 961228
419 + 960809 = 961228

Showing the first eight; more decompositions exist.
