Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542152, here are decompositions:

3 + 542149 = 542152
11 + 542141 = 542152
29 + 542123 = 542152
41 + 542111 = 542152
59 + 542093 = 542152
71 + 542081 = 542152
89 + 542063 = 542152
131 + 542021 = 542152

Showing the first eight; more decompositions exist.
