Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522254, here are decompositions:

3 + 522251 = 522254
43 + 522211 = 522254
97 + 522157 = 522254
127 + 522127 = 522254
181 + 522073 = 522254
193 + 522061 = 522254
331 + 521923 = 522254
367 + 521887 = 522254

Showing the first eight; more decompositions exist.
