Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8522, here are decompositions:

61 + 8461 = 8522
79 + 8443 = 8522
103 + 8419 = 8522
193 + 8329 = 8522
211 + 8311 = 8522
229 + 8293 = 8522
313 + 8209 = 8522
331 + 8191 = 8522

Showing the first eight; more decompositions exist.
