Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997766, here are decompositions:

67 + 997699 = 997766
73 + 997693 = 997766
103 + 997663 = 997766
139 + 997627 = 997766
157 + 997609 = 997766
193 + 997573 = 997766
313 + 997453 = 997766
397 + 997369 = 997766

Showing the first eight; more decompositions exist.
