Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542790, here are decompositions:

7 + 542783 = 542790
19 + 542771 = 542790
29 + 542761 = 542790
43 + 542747 = 542790
67 + 542723 = 542790
71 + 542719 = 542790
97 + 542693 = 542790
103 + 542687 = 542790

Showing the first eight; more decompositions exist.
