Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997618, here are decompositions:

29 + 997589 = 997618
71 + 997547 = 997618
107 + 997511 = 997618
179 + 997439 = 997618
191 + 997427 = 997618
227 + 997391 = 997618
239 + 997379 = 997618
311 + 997307 = 997618

Showing the first eight; more decompositions exist.
