Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501740, here are decompositions:

37 + 501703 = 501740
103 + 501637 = 501740
139 + 501601 = 501740
163 + 501577 = 501740
229 + 501511 = 501740
277 + 501463 = 501740
313 + 501427 = 501740
331 + 501409 = 501740

Showing the first eight; more decompositions exist.
