Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697842, here are decompositions:

19 + 8697823 = 8697842
31 + 8697811 = 8697842
73 + 8697769 = 8697842
151 + 8697691 = 8697842
229 + 8697613 = 8697842
331 + 8697511 = 8697842
409 + 8697433 = 8697842
463 + 8697379 = 8697842

Showing the first eight; more decompositions exist.
