Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997392, here are decompositions:

13 + 997379 = 997392
23 + 997369 = 997392
59 + 997333 = 997392
73 + 997319 = 997392
83 + 997309 = 997392
113 + 997279 = 997392
173 + 997219 = 997392
191 + 997201 = 997392

Showing the first eight; more decompositions exist.
