Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997590, here are decompositions:

7 + 997583 = 997590
17 + 997573 = 997590
37 + 997553 = 997590
43 + 997547 = 997590
79 + 997511 = 997590
127 + 997463 = 997590
137 + 997453 = 997590
151 + 997439 = 997590

Showing the first eight; more decompositions exist.
