Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942428, here are decompositions:

61 + 942367 = 942428
127 + 942301 = 942428
181 + 942247 = 942428
211 + 942217 = 942428
229 + 942199 = 942428
241 + 942187 = 942428
337 + 942091 = 942428
349 + 942079 = 942428

Showing the first eight; more decompositions exist.
