Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997586, here are decompositions:

3 + 997583 = 997586
13 + 997573 = 997586
229 + 997357 = 997586
277 + 997309 = 997586
307 + 997279 = 997586
313 + 997273 = 997586
367 + 997219 = 997586
379 + 997207 = 997586

Showing the first eight; more decompositions exist.
