Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511532, here are decompositions:

13 + 511519 = 511532
79 + 511453 = 511532
181 + 511351 = 511532
199 + 511333 = 511532
271 + 511261 = 511532
331 + 511201 = 511532
379 + 511153 = 511532
409 + 511123 = 511532

Showing the first eight; more decompositions exist.
