Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542998, here are decompositions:

11 + 542987 = 542998
17 + 542981 = 542998
47 + 542951 = 542998
59 + 542939 = 542998
107 + 542891 = 542998
167 + 542831 = 542998
227 + 542771 = 542998
251 + 542747 = 542998

Showing the first eight; more decompositions exist.
