Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537220, here are decompositions:

23 + 537197 = 537220
29 + 537191 = 537220
149 + 537071 = 537220
179 + 537041 = 537220
191 + 537029 = 537220
197 + 537023 = 537220
311 + 536909 = 537220
353 + 536867 = 537220

Showing the first eight; more decompositions exist.
