Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525508, here are decompositions:

17 + 525491 = 525508
41 + 525467 = 525508
47 + 525461 = 525508
131 + 525377 = 525508
149 + 525359 = 525508
251 + 525257 = 525508
317 + 525191 = 525508
479 + 525029 = 525508

Showing the first eight; more decompositions exist.
