Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997522, here are decompositions:

11 + 997511 = 997522
59 + 997463 = 997522
83 + 997439 = 997522
89 + 997433 = 997522
131 + 997391 = 997522
179 + 997343 = 997522
263 + 997259 = 997522
359 + 997163 = 997522

Showing the first eight; more decompositions exist.
