Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542778, here are decompositions:

7 + 542771 = 542778
17 + 542761 = 542778
31 + 542747 = 542778
59 + 542719 = 542778
179 + 542599 = 542778
191 + 542587 = 542778
199 + 542579 = 542778
211 + 542567 = 542778

Showing the first eight; more decompositions exist.
