Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542980, here are decompositions:

29 + 542951 = 542980
41 + 542939 = 542980
47 + 542933 = 542980
59 + 542921 = 542980
89 + 542891 = 542980
107 + 542873 = 542980
149 + 542831 = 542980
197 + 542783 = 542980

Showing the first eight; more decompositions exist.
