Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945880, here are decompositions:

29 + 945851 = 945880
71 + 945809 = 945880
113 + 945767 = 945880
149 + 945731 = 945880
179 + 945701 = 945880
233 + 945647 = 945880
251 + 945629 = 945880
293 + 945587 = 945880

Showing the first eight; more decompositions exist.
