Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997782, here are decompositions:

13 + 997769 = 997782
31 + 997751 = 997782
41 + 997741 = 997782
43 + 997739 = 997782
83 + 997699 = 997782
89 + 997693 = 997782
101 + 997681 = 997782
131 + 997651 = 997782

Showing the first eight; more decompositions exist.
