Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542628, here are decompositions:

29 + 542599 = 542628
41 + 542587 = 542628
61 + 542567 = 542628
71 + 542557 = 542628
89 + 542539 = 542628
109 + 542519 = 542628
131 + 542497 = 542628
139 + 542489 = 542628

Showing the first eight; more decompositions exist.
