Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540542, here are decompositions:

3 + 540539 = 540542
31 + 540511 = 540542
73 + 540469 = 540542
109 + 540433 = 540542
151 + 540391 = 540542
193 + 540349 = 540542
199 + 540343 = 540542
241 + 540301 = 540542

Showing the first eight; more decompositions exist.
