Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501636, here are decompositions:

13 + 501623 = 501636
19 + 501617 = 501636
43 + 501593 = 501636
59 + 501577 = 501636
73 + 501563 = 501636
173 + 501463 = 501636
227 + 501409 = 501636
269 + 501367 = 501636

Showing the first eight; more decompositions exist.
