Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500242, here are decompositions:

3 + 500239 = 500242
5 + 500237 = 500242
11 + 500231 = 500242
89 + 500153 = 500242
131 + 500111 = 500242
173 + 500069 = 500242
233 + 500009 = 500242
263 + 499979 = 500242

Showing the first eight; more decompositions exist.
