Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542678, here are decompositions:

79 + 542599 = 542678
127 + 542551 = 542678
139 + 542539 = 542678
181 + 542497 = 542678
211 + 542467 = 542678
277 + 542401 = 542678
307 + 542371 = 542678
379 + 542299 = 542678

Showing the first eight; more decompositions exist.
