Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542986, here are decompositions:

5 + 542981 = 542986
47 + 542939 = 542986
53 + 542933 = 542986
113 + 542873 = 542986
149 + 542837 = 542986
239 + 542747 = 542986
263 + 542723 = 542986
293 + 542693 = 542986

Showing the first eight; more decompositions exist.
