Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511698, here are decompositions:

7 + 511691 = 511698
29 + 511669 = 511698
67 + 511631 = 511698
71 + 511627 = 511698
107 + 511591 = 511698
139 + 511559 = 511698
149 + 511549 = 511698
157 + 511541 = 511698

Showing the first eight; more decompositions exist.
