Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997814, here are decompositions:

3 + 997811 = 997814
7 + 997807 = 997814
31 + 997783 = 997814
73 + 997741 = 997814
151 + 997663 = 997814
163 + 997651 = 997814
241 + 997573 = 997814
457 + 997357 = 997814

Showing the first eight; more decompositions exist.
