Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518572, here are decompositions:

29 + 518543 = 518572
101 + 518471 = 518572
281 + 518291 = 518572
311 + 518261 = 518572
401 + 518171 = 518572
419 + 518153 = 518572
443 + 518129 = 518572
449 + 518123 = 518572

Showing the first eight; more decompositions exist.
