Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540228, here are decompositions:

11 + 540217 = 540228
41 + 540187 = 540228
47 + 540181 = 540228
61 + 540167 = 540228
71 + 540157 = 540228
79 + 540149 = 540228
89 + 540139 = 540228
107 + 540121 = 540228

Showing the first eight; more decompositions exist.
