Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942438, here are decompositions:

5 + 942433 = 942438
37 + 942401 = 942438
67 + 942371 = 942438
71 + 942367 = 942438
97 + 942341 = 942438
127 + 942311 = 942438
137 + 942301 = 942438
181 + 942257 = 942438

Showing the first eight; more decompositions exist.
