Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540222, here are decompositions:

5 + 540217 = 540222
19 + 540203 = 540222
41 + 540181 = 540222
43 + 540179 = 540222
73 + 540149 = 540222
83 + 540139 = 540222
101 + 540121 = 540222
103 + 540119 = 540222

Showing the first eight; more decompositions exist.
