Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542688, here are decompositions:

5 + 542683 = 542688
89 + 542599 = 542688
101 + 542587 = 542688
109 + 542579 = 542688
131 + 542557 = 542688
137 + 542551 = 542688
149 + 542539 = 542688
151 + 542537 = 542688

Showing the first eight; more decompositions exist.
