Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542442, here are decompositions:

41 + 542401 = 542442
71 + 542371 = 542442
149 + 542293 = 542442
179 + 542263 = 542442
181 + 542261 = 542442
191 + 542251 = 542442
223 + 542219 = 542442
293 + 542149 = 542442

Showing the first eight; more decompositions exist.
