Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938442, here are decompositions:

5 + 938437 = 938442
73 + 938369 = 938442
83 + 938359 = 938442
101 + 938341 = 938442
149 + 938293 = 938442
163 + 938279 = 938442
179 + 938263 = 938442
191 + 938251 = 938442

Showing the first eight; more decompositions exist.
