Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511156, here are decompositions:

3 + 511153 = 511156
5 + 511151 = 511156
47 + 511109 = 511156
137 + 511019 = 511156
167 + 510989 = 511156
353 + 510803 = 511156
383 + 510773 = 511156
389 + 510767 = 511156

Showing the first eight; more decompositions exist.
