Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511672, here are decompositions:

3 + 511669 = 511672
41 + 511631 = 511672
89 + 511583 = 511672
113 + 511559 = 511672
131 + 511541 = 511672
149 + 511523 = 511672
233 + 511439 = 511672
263 + 511409 = 511672

Showing the first eight; more decompositions exist.
