Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540238, here are decompositions:

5 + 540233 = 540238
59 + 540179 = 540238
71 + 540167 = 540238
89 + 540149 = 540238
137 + 540101 = 540238
197 + 540041 = 540238
317 + 539921 = 540238
389 + 539849 = 540238

Showing the first eight; more decompositions exist.
