Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542226, here are decompositions:

7 + 542219 = 542226
19 + 542207 = 542226
29 + 542197 = 542226
37 + 542189 = 542226
43 + 542183 = 542226
59 + 542167 = 542226
73 + 542153 = 542226
103 + 542123 = 542226

Showing the first eight; more decompositions exist.
