Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542086, here are decompositions:

3 + 542083 = 542086
5 + 542081 = 542086
23 + 542063 = 542086
59 + 542027 = 542086
197 + 541889 = 542086
227 + 541859 = 542086
269 + 541817 = 542086
359 + 541727 = 542086

Showing the first eight; more decompositions exist.
