Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511158, here are decompositions:

5 + 511153 = 511158
7 + 511151 = 511158
47 + 511111 = 511158
71 + 511087 = 511158
97 + 511061 = 511158
101 + 511057 = 511158
139 + 511019 = 511158
157 + 511001 = 511158

Showing the first eight; more decompositions exist.
