Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997520, here are decompositions:

67 + 997453 = 997520
151 + 997369 = 997520
163 + 997357 = 997520
193 + 997327 = 997520
211 + 997309 = 997520
241 + 997279 = 997520
313 + 997207 = 997520
367 + 997153 = 997520

Showing the first eight; more decompositions exist.
