Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537238, here are decompositions:

5 + 537233 = 537238
17 + 537221 = 537238
41 + 537197 = 537238
47 + 537191 = 537238
167 + 537071 = 537238
197 + 537041 = 537238
227 + 537011 = 537238
239 + 536999 = 537238

Showing the first eight; more decompositions exist.
