Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945980, here are decompositions:

19 + 945961 = 945980
31 + 945949 = 945980
37 + 945943 = 945980
43 + 945937 = 945980
73 + 945907 = 945980
97 + 945883 = 945980
157 + 945823 = 945980
163 + 945817 = 945980

Showing the first eight; more decompositions exist.
