Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540372, here are decompositions:

5 + 540367 = 540372
23 + 540349 = 540372
29 + 540343 = 540372
71 + 540301 = 540372
89 + 540283 = 540372
101 + 540271 = 540372
103 + 540269 = 540372
139 + 540233 = 540372

Showing the first eight; more decompositions exist.
