Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542266, here are decompositions:

3 + 542263 = 542266
5 + 542261 = 542266
29 + 542237 = 542266
47 + 542219 = 542266
59 + 542207 = 542266
83 + 542183 = 542266
113 + 542153 = 542266
149 + 542117 = 542266

Showing the first eight; more decompositions exist.
