Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997712, here are decompositions:

13 + 997699 = 997712
19 + 997693 = 997712
31 + 997681 = 997712
61 + 997651 = 997712
103 + 997609 = 997712
139 + 997573 = 997712
379 + 997333 = 997712
433 + 997279 = 997712

Showing the first eight; more decompositions exist.
