Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540558, here are decompositions:

17 + 540541 = 540558
19 + 540539 = 540558
41 + 540517 = 540558
47 + 540511 = 540558
89 + 540469 = 540558
97 + 540461 = 540558
167 + 540391 = 540558
181 + 540377 = 540558

Showing the first eight; more decompositions exist.
