Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522206, here are decompositions:

7 + 522199 = 522206
79 + 522127 = 522206
127 + 522079 = 522206
277 + 521929 = 522206
283 + 521923 = 522206
337 + 521869 = 522206
397 + 521809 = 522206
439 + 521767 = 522206

Showing the first eight; more decompositions exist.
