Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511700, here are decompositions:

31 + 511669 = 511700
67 + 511633 = 511700
73 + 511627 = 511700
97 + 511603 = 511700
109 + 511591 = 511700
127 + 511573 = 511700
151 + 511549 = 511700
181 + 511519 = 511700

Showing the first eight; more decompositions exist.
