Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537538, here are decompositions:

11 + 537527 = 537538
41 + 537497 = 537538
137 + 537401 = 537538
191 + 537347 = 537538
251 + 537287 = 537538
257 + 537281 = 537538
269 + 537269 = 537538
317 + 537221 = 537538

Showing the first eight; more decompositions exist.
