Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542400, here are decompositions:

29 + 542371 = 542400
101 + 542299 = 542400
107 + 542293 = 542400
137 + 542263 = 542400
139 + 542261 = 542400
149 + 542251 = 542400
163 + 542237 = 542400
181 + 542219 = 542400

Showing the first eight; more decompositions exist.
