Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540428, here are decompositions:

37 + 540391 = 540428
61 + 540367 = 540428
79 + 540349 = 540428
127 + 540301 = 540428
157 + 540271 = 540428
211 + 540217 = 540428
241 + 540187 = 540428
271 + 540157 = 540428

Showing the first eight; more decompositions exist.
