Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530432, here are decompositions:

3 + 530429 = 530432
31 + 530401 = 530432
43 + 530389 = 530432
73 + 530359 = 530432
79 + 530353 = 530432
103 + 530329 = 530432
139 + 530293 = 530432
181 + 530251 = 530432

Showing the first eight; more decompositions exist.
