Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501572, here are decompositions:

61 + 501511 = 501572
79 + 501493 = 501572
109 + 501463 = 501572
163 + 501409 = 501572
229 + 501343 = 501572
349 + 501223 = 501572
433 + 501139 = 501572
439 + 501133 = 501572

Showing the first eight; more decompositions exist.
