Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997636, here are decompositions:

47 + 997589 = 997636
53 + 997583 = 997636
83 + 997553 = 997636
89 + 997547 = 997636
173 + 997463 = 997636
197 + 997439 = 997636
257 + 997379 = 997636
293 + 997343 = 997636

Showing the first eight; more decompositions exist.
