Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542854, here are decompositions:

17 + 542837 = 542854
23 + 542831 = 542854
71 + 542783 = 542854
83 + 542771 = 542854
107 + 542747 = 542854
131 + 542723 = 542854
167 + 542687 = 542854
251 + 542603 = 542854

Showing the first eight; more decompositions exist.
