Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511230, here are decompositions:

7 + 511223 = 511230
17 + 511213 = 511230
19 + 511211 = 511230
29 + 511201 = 511230
37 + 511193 = 511230
53 + 511177 = 511230
59 + 511171 = 511230
61 + 511169 = 511230

Showing the first eight; more decompositions exist.
