Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500278, here are decompositions:

29 + 500249 = 500278
41 + 500237 = 500278
47 + 500231 = 500278
101 + 500177 = 500278
167 + 500111 = 500278
269 + 500009 = 500278
491 + 499787 = 500278
587 + 499691 = 500278

Showing the first eight; more decompositions exist.
