Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542280, here are decompositions:

17 + 542263 = 542280
19 + 542261 = 542280
29 + 542251 = 542280
43 + 542237 = 542280
61 + 542219 = 542280
73 + 542207 = 542280
83 + 542197 = 542280
97 + 542183 = 542280

Showing the first eight; more decompositions exist.
