Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542824, here are decompositions:

3 + 542821 = 542824
41 + 542783 = 542824
53 + 542771 = 542824
101 + 542723 = 542824
131 + 542693 = 542824
137 + 542687 = 542824
257 + 542567 = 542824
383 + 542441 = 542824

Showing the first eight; more decompositions exist.
