Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540220, here are decompositions:

3 + 540217 = 540220
17 + 540203 = 540220
41 + 540179 = 540220
47 + 540173 = 540220
53 + 540167 = 540220
71 + 540149 = 540220
101 + 540119 = 540220
179 + 540041 = 540220

Showing the first eight; more decompositions exist.
