Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540432, here are decompositions:

41 + 540391 = 540432
43 + 540389 = 540432
59 + 540373 = 540432
83 + 540349 = 540432
89 + 540343 = 540432
131 + 540301 = 540432
149 + 540283 = 540432
163 + 540269 = 540432

Showing the first eight; more decompositions exist.
