Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942420, here are decompositions:

19 + 942401 = 942420
53 + 942367 = 942420
79 + 942341 = 942420
103 + 942317 = 942420
107 + 942313 = 942420
109 + 942311 = 942420
151 + 942269 = 942420
163 + 942257 = 942420

Showing the first eight; more decompositions exist.
