Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540290, here are decompositions:

7 + 540283 = 540290
19 + 540271 = 540290
73 + 540217 = 540290
103 + 540187 = 540290
109 + 540181 = 540290
151 + 540139 = 540290
211 + 540079 = 540290
229 + 540061 = 540290

Showing the first eight; more decompositions exist.
