Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542244, here are decompositions:

7 + 542237 = 542244
37 + 542207 = 542244
47 + 542197 = 542244
61 + 542183 = 542244
103 + 542141 = 542244
113 + 542131 = 542244
127 + 542117 = 542244
151 + 542093 = 542244

Showing the first eight; more decompositions exist.
