Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501620, here are decompositions:

3 + 501617 = 501620
19 + 501601 = 501620
43 + 501577 = 501620
109 + 501511 = 501620
127 + 501493 = 501620
157 + 501463 = 501620
193 + 501427 = 501620
211 + 501409 = 501620

Showing the first eight; more decompositions exist.
