Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997508, here are decompositions:

139 + 997369 = 997508
151 + 997357 = 997508
181 + 997327 = 997508
199 + 997309 = 997508
229 + 997279 = 997508
241 + 997267 = 997508
307 + 997201 = 997508
367 + 997141 = 997508

Showing the first eight; more decompositions exist.
