Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542402, here are decompositions:

31 + 542371 = 542402
79 + 542323 = 542402
103 + 542299 = 542402
109 + 542293 = 542402
139 + 542263 = 542402
151 + 542251 = 542402
271 + 542131 = 542402
283 + 542119 = 542402

Showing the first eight; more decompositions exist.
