Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542150, here are decompositions:

19 + 542131 = 542150
31 + 542119 = 542150
67 + 542083 = 542150
79 + 542071 = 542150
97 + 542053 = 542150
127 + 542023 = 542150
151 + 541999 = 542150
157 + 541993 = 542150

Showing the first eight; more decompositions exist.
