Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542146, here are decompositions:

5 + 542141 = 542146
23 + 542123 = 542146
29 + 542117 = 542146
53 + 542093 = 542146
83 + 542063 = 542146
179 + 541967 = 542146
257 + 541889 = 542146
347 + 541799 = 542146

Showing the first eight; more decompositions exist.
