Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542722, here are decompositions:

3 + 542719 = 542722
29 + 542693 = 542722
233 + 542489 = 542722
239 + 542483 = 542722
281 + 542441 = 542722
461 + 542261 = 542722
503 + 542219 = 542722
569 + 542153 = 542722

Showing the first eight; more decompositions exist.
