Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522446, here are decompositions:

7 + 522439 = 522446
37 + 522409 = 522446
73 + 522373 = 522446
109 + 522337 = 522446
157 + 522289 = 522446
163 + 522283 = 522446
367 + 522079 = 522446
373 + 522073 = 522446

Showing the first eight; more decompositions exist.
