Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997540, here are decompositions:

29 + 997511 = 997540
101 + 997439 = 997540
107 + 997433 = 997540
113 + 997427 = 997540
149 + 997391 = 997540
197 + 997343 = 997540
233 + 997307 = 997540
281 + 997259 = 997540

Showing the first eight; more decompositions exist.
