Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522380, here are decompositions:

7 + 522373 = 522380
43 + 522337 = 522380
97 + 522283 = 522380
151 + 522229 = 522380
181 + 522199 = 522380
223 + 522157 = 522380
307 + 522073 = 522380
457 + 521923 = 522380

Showing the first eight; more decompositions exist.
