Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532, here are decompositions:

11 + 521 = 532
23 + 509 = 532
29 + 503 = 532
41 + 491 = 532
53 + 479 = 532
71 + 461 = 532
83 + 449 = 532
89 + 443 = 532

Showing the first eight; more decompositions exist.
