Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542738, here are decompositions:

19 + 542719 = 542738
139 + 542599 = 542738
151 + 542587 = 542738
181 + 542557 = 542738
199 + 542539 = 542738
241 + 542497 = 542738
271 + 542467 = 542738
277 + 542461 = 542738

Showing the first eight; more decompositions exist.
