Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542272, here are decompositions:

11 + 542261 = 542272
53 + 542219 = 542272
83 + 542189 = 542272
89 + 542183 = 542272
131 + 542141 = 542272
149 + 542123 = 542272
179 + 542093 = 542272
191 + 542081 = 542272

Showing the first eight; more decompositions exist.
