Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542826, here are decompositions:

5 + 542821 = 542826
29 + 542797 = 542826
43 + 542783 = 542826
79 + 542747 = 542826
103 + 542723 = 542826
107 + 542719 = 542826
113 + 542713 = 542826
139 + 542687 = 542826

Showing the first eight; more decompositions exist.
