Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997772, here are decompositions:

3 + 997769 = 997772
31 + 997741 = 997772
73 + 997699 = 997772
79 + 997693 = 997772
109 + 997663 = 997772
163 + 997609 = 997772
199 + 997573 = 997772
439 + 997333 = 997772

Showing the first eight; more decompositions exist.
