Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542782, here are decompositions:

11 + 542771 = 542782
59 + 542723 = 542782
89 + 542693 = 542782
179 + 542603 = 542782
263 + 542519 = 542782
293 + 542489 = 542782
521 + 542261 = 542782
563 + 542219 = 542782

Showing the first eight; more decompositions exist.
