Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542530, here are decompositions:

11 + 542519 = 542530
41 + 542489 = 542530
47 + 542483 = 542530
83 + 542447 = 542530
89 + 542441 = 542530
269 + 542261 = 542530
293 + 542237 = 542530
311 + 542219 = 542530

Showing the first eight; more decompositions exist.
