Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501994, here are decompositions:

23 + 501971 = 501994
41 + 501953 = 501994
47 + 501947 = 501994
83 + 501911 = 501994
131 + 501863 = 501994
167 + 501827 = 501994
173 + 501821 = 501994
191 + 501803 = 501994

Showing the first eight; more decompositions exist.
