Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542802, here are decompositions:

5 + 542797 = 542802
11 + 542791 = 542802
19 + 542783 = 542802
31 + 542771 = 542802
41 + 542761 = 542802
79 + 542723 = 542802
83 + 542719 = 542802
89 + 542713 = 542802

Showing the first eight; more decompositions exist.
