Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501564, here are decompositions:

53 + 501511 = 501564
61 + 501503 = 501564
71 + 501493 = 501564
101 + 501463 = 501564
113 + 501451 = 501564
137 + 501427 = 501564
163 + 501401 = 501564
181 + 501383 = 501564

Showing the first eight; more decompositions exist.
