Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500158, here are decompositions:

5 + 500153 = 500158
47 + 500111 = 500158
89 + 500069 = 500158
101 + 500057 = 500158
149 + 500009 = 500158
179 + 499979 = 500158
419 + 499739 = 500158
467 + 499691 = 500158

Showing the first eight; more decompositions exist.
