Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511446, here are decompositions:

7 + 511439 = 511446
29 + 511417 = 511446
37 + 511409 = 511446
59 + 511387 = 511446
109 + 511337 = 511446
113 + 511333 = 511446
149 + 511297 = 511446
157 + 511289 = 511446

Showing the first eight; more decompositions exist.
