Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540452, here are decompositions:

19 + 540433 = 540452
61 + 540391 = 540452
79 + 540373 = 540452
103 + 540349 = 540452
109 + 540343 = 540452
151 + 540301 = 540452
181 + 540271 = 540452
271 + 540181 = 540452

Showing the first eight; more decompositions exist.
