Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511836, here are decompositions:

5 + 511831 = 511836
43 + 511793 = 511836
79 + 511757 = 511836
113 + 511723 = 511836
167 + 511669 = 511836
233 + 511603 = 511836
257 + 511579 = 511836
263 + 511573 = 511836

Showing the first eight; more decompositions exist.
