Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511578, here are decompositions:

5 + 511573 = 511578
19 + 511559 = 511578
29 + 511549 = 511578
37 + 511541 = 511578
59 + 511519 = 511578
71 + 511507 = 511578
101 + 511477 = 511578
131 + 511447 = 511578

Showing the first eight; more decompositions exist.
