Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542898, here are decompositions:

7 + 542891 = 542898
61 + 542837 = 542898
67 + 542831 = 542898
101 + 542797 = 542898
107 + 542791 = 542898
127 + 542771 = 542898
137 + 542761 = 542898
151 + 542747 = 542898

Showing the first eight; more decompositions exist.
