Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997928, here are decompositions:

31 + 997897 = 997928
37 + 997891 = 997928
229 + 997699 = 997928
277 + 997651 = 997928
331 + 997597 = 997928
571 + 997357 = 997928
601 + 997327 = 997928
619 + 997309 = 997928

Showing the first eight; more decompositions exist.
