Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525542, here are decompositions:

13 + 525529 = 525542
103 + 525439 = 525542
109 + 525433 = 525542
151 + 525391 = 525542
163 + 525379 = 525542
181 + 525361 = 525542
229 + 525313 = 525542
349 + 525193 = 525542

Showing the first eight; more decompositions exist.
