Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997684, here are decompositions:

3 + 997681 = 997684
47 + 997637 = 997684
101 + 997583 = 997684
131 + 997553 = 997684
137 + 997547 = 997684
173 + 997511 = 997684
251 + 997433 = 997684
257 + 997427 = 997684

Showing the first eight; more decompositions exist.
