Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542830, here are decompositions:

47 + 542783 = 542830
59 + 542771 = 542830
83 + 542747 = 542830
107 + 542723 = 542830
137 + 542693 = 542830
227 + 542603 = 542830
251 + 542579 = 542830
263 + 542567 = 542830

Showing the first eight; more decompositions exist.
