Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537572, here are decompositions:

3 + 537569 = 537572
193 + 537379 = 537572
199 + 537373 = 537572
229 + 537343 = 537572
241 + 537331 = 537572
331 + 537241 = 537572
439 + 537133 = 537572
571 + 537001 = 537572

Showing the first eight; more decompositions exist.
