Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525506, here are decompositions:

13 + 525493 = 525506
67 + 525439 = 525506
73 + 525433 = 525506
97 + 525409 = 525506
109 + 525397 = 525506
127 + 525379 = 525506
193 + 525313 = 525506
307 + 525199 = 525506

Showing the first eight; more decompositions exist.
