Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511282, here are decompositions:

3 + 511279 = 511282
59 + 511223 = 511282
71 + 511211 = 511282
89 + 511193 = 511282
113 + 511169 = 511282
131 + 511151 = 511282
173 + 511109 = 511282
263 + 511019 = 511282

Showing the first eight; more decompositions exist.
