Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525532, here are decompositions:

3 + 525529 = 525532
41 + 525491 = 525532
71 + 525461 = 525532
101 + 525431 = 525532
173 + 525359 = 525532
179 + 525353 = 525532
233 + 525299 = 525532
311 + 525221 = 525532

Showing the first eight; more decompositions exist.
