Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542078, here are decompositions:

7 + 542071 = 542078
79 + 541999 = 542078
127 + 541951 = 542078
151 + 541927 = 542078
241 + 541837 = 542078
307 + 541771 = 542078
367 + 541711 = 542078
379 + 541699 = 542078

Showing the first eight; more decompositions exist.
