Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521532, here are decompositions:

5 + 521527 = 521532
13 + 521519 = 521532
29 + 521503 = 521532
41 + 521491 = 521532
61 + 521471 = 521532
103 + 521429 = 521532
131 + 521401 = 521532
139 + 521393 = 521532

Showing the first eight; more decompositions exist.
