Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501748, here are decompositions:

17 + 501731 = 501748
29 + 501719 = 501748
41 + 501707 = 501748
47 + 501701 = 501748
89 + 501659 = 501748
131 + 501617 = 501748
347 + 501401 = 501748
431 + 501317 = 501748

Showing the first eight; more decompositions exist.
