Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501540, here are decompositions:

29 + 501511 = 501540
37 + 501503 = 501540
47 + 501493 = 501540
89 + 501451 = 501540
113 + 501427 = 501540
131 + 501409 = 501540
139 + 501401 = 501540
157 + 501383 = 501540

Showing the first eight; more decompositions exist.
