Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525442, here are decompositions:

3 + 525439 = 525442
11 + 525431 = 525442
83 + 525359 = 525442
89 + 525353 = 525442
233 + 525209 = 525442
251 + 525191 = 525442
443 + 524999 = 525442
461 + 524981 = 525442

Showing the first eight; more decompositions exist.
