Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542918, here are decompositions:

7 + 542911 = 542918
97 + 542821 = 542918
127 + 542791 = 542918
157 + 542761 = 542918
199 + 542719 = 542918
331 + 542587 = 542918
367 + 542551 = 542918
379 + 542539 = 542918

Showing the first eight; more decompositions exist.
