Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542842, here are decompositions:

5 + 542837 = 542842
11 + 542831 = 542842
59 + 542783 = 542842
71 + 542771 = 542842
149 + 542693 = 542842
239 + 542603 = 542842
263 + 542579 = 542842
353 + 542489 = 542842

Showing the first eight; more decompositions exist.
