Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697738, here are decompositions:

31 + 8697707 = 8697738
41 + 8697697 = 8697738
47 + 8697691 = 8697738
61 + 8697677 = 8697738
97 + 8697641 = 8697738
131 + 8697607 = 8697738
139 + 8697599 = 8697738
151 + 8697587 = 8697738

Showing the first eight; more decompositions exist.
