Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542920, here are decompositions:

29 + 542891 = 542920
47 + 542873 = 542920
83 + 542837 = 542920
89 + 542831 = 542920
137 + 542783 = 542920
149 + 542771 = 542920
173 + 542747 = 542920
197 + 542723 = 542920

Showing the first eight; more decompositions exist.
