Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945838, here are decompositions:

29 + 945809 = 945838
71 + 945767 = 945838
107 + 945731 = 945838
137 + 945701 = 945838
167 + 945671 = 945838
191 + 945647 = 945838
251 + 945587 = 945838
317 + 945521 = 945838

Showing the first eight; more decompositions exist.
