Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542278, here are decompositions:

17 + 542261 = 542278
41 + 542237 = 542278
59 + 542219 = 542278
71 + 542207 = 542278
89 + 542189 = 542278
137 + 542141 = 542278
167 + 542111 = 542278
197 + 542081 = 542278

Showing the first eight; more decompositions exist.
